This seasonal two-parter takes place two years after Kate's death, with Sarah Lancashire's Caroline taking up a job at an underperforming school in Huddersfield, much to the chagrin of her family. Meanwhile, a nasty accident involving Robbie triggers haunting memories for Gillian, and ever-exasperating Celia (Anne Reid) ropes Alan into amateur dramatics, prompting a memorable protest from Derek Jacobi of "I can't act!"

A fixture on our best of the year list since it began in 2012, Last Tango in Halifax proved once again to be one of the best dramas on the BBC this year. Sally Wainwright's characters are so well drawn coupled with wonderful performances from Sarah Lancashire, Nicola Walker and Anne Reid. It's a series that never takes the obvious direction and still provides its audience with surprises.

Older women coming out as lesbians thanks to BBC

Older women have been coming out as lesbians after being inspired by Last Tango In Halifax, its star Sarah Lancashire says.

One return I am excited about is that of Last Tango in Halifax which was announced on Twitter just after this Sunday's magnificent series three finale. Sally Wainwright's brilliant ear for dialogue was on full display as Gillian (Nicola Walker) voiced her doubts about marrying boorish childhood sweetheart Robbie (Dean Andrews). The structure of the piece saw Wainwright apply a non-linear narrative as Gillian flashed back to tell Caroline (Sarah Lancashire) about her dalliances with a younger co-worker as well as Caroline's ex-husband John (Tony Gardner). The realistic sequences were punctuated with some high comedy as Caroline struggled to change a tyre whilst wearing her Sunday best whilst Robbie looked on the verge of vomiting after overdoing it on his stag night the prior evening. Wainwright kept the audience guessing whether Gillian would marry Robbie while she also focused on the frosty relationship between Alan (Derek Jacobi) and his love child Gary (Rupert Graves). As the camera swept round the multitude of happy couples at Robbie and Gillian's wedding it reminded me just how much Wainwright had made me care about her characters. I'd wept with Caroline after she'd lost her partner and felt for Gillian as she drudged up the abuse that her late husband inflicted on her. Wainwright has been lucky to find an excellent ensemble cast who deal with her well-paced dialogue beautifully. Special mention has to go to Walker who is utterly believable, playing the likeable Gillian who is prone to making some terrible mistakes. The only criticism I have is the continued presence of Gardner's John who at this point I feel is surplus to requirements and I hope he doesn't return for series four. Apart from that though I would say that this is Last Tango's best series to date and I'm already ridiculously excited about what series four will bring.

Radio Times review

It's Gillian's wedding day as the series ends, and she won't leave the bathroom. It could be a last-minute fluttering of bride-to-be panic or it could be something deeper.

Of course, this is Last Tango, written by Sally Wainwright, so it's something much deeper than whether that charmless oaf Robbie is really the man for Gillian. And don't go expecting one of those soapy, pragmatic bits of plotting where we are left wondering will she?/won't she? just for the sake of it. Gillian (brilliant Nicola Walker) has much she needs to get off her chest and she offloads on a woman who's become a good friend, Caroline (Sarah Lancashire, also brilliant).

I love the conversations between these two - sometimes hesitant, always revealing, as they share the stuff of their souls. Gillian is weary of being dumped on by her family, while Caroline carefully puts her grief to one side to offer wise counsel.

Radio Times review

Caroline has to adapt to her dramatic new family circumstances and she's finding it hard, but for once her mum Celia is kind and sympathetic. Of course, Celia refused to attend her daughter's wedding to Kate, but life ebbs and flows, and grievances can't be nursed for long.

Writer Sally Wainwright is so gifted and assured when it comes to calling out to our emotions: no one is more precise at picking apart the mechanics of relationships, particularly relationships between women. She's blessed with a great cast and there are some scenes tonight between Anne Reid and Sarah Lancashire (Celia and Caroline) that will take away pieces of your heart.

But Last Tango isn't just about a mother and daughter; it's about the trials of a big extended family, including Gillian (Nicola Walker), who's about to take a big leap.

Sarah Lancashire shines in a fantastic instalment!

When series three of Last Tango in Halifax first started I definitely had my reservations especially in regards to the character of Alan's long-lost son Gary. However, Sally Wainwright's script has taken the story into a whole direction.

Last Tango in Halifax began it's third series late last year and reunited us with Alan (Derek Jacobi) and Celia (Anne Reid) as well as their respective broods. I've been a fan of Last Tango since it first began and particularly liked the darker second series which explored the past of Gillian (Nicola Walker) in a lot more detail. With Last Tango's writer Sally Wainwright busying herself with Happy Valley in 2014, I felt that she may not have enough time to wholly devote herself to a third series of this excellent family drama. These fears were compounded by the major story running throughout the first episode in which it was revealed that Alan had a secret son, Gary (Rupert Graves), who was the result of a brief affair Alan had conducted. The introduction of Gary to me felt like a way of just putting another obstacle in the way of the drama's central couple's happiness. However, after a lacklustre opener, Last Tango really kicked in in episode two as the emotional fallout from Gary's arrival started to take its toll on Celia. Celia's realisation that Alan wasn't completely perfect left her reeling and as a result she decided not to attend the wedding of her daughter Caroline (Sarah Lancashire) and her partner Kate (Nina Sosanya). This second episode completely restored my faith in Wainwright's storytelling abilities and it's clear that she knows her characters inside out, a fact witnessed by the icy way Caroline ejected Alan from her wedding.

Indeed, as somebody who has watched the series since it first started, I feel like I know these characters and therefore their reactions feel utterly genuine. That's possibly why I initially rejected the introduction of Gary into the series, however episode two gave Rupert Graves the opportunity to flesh out the character a little more. But Last Tango in Halifax wouldn't be nearly as good as it is if it were not for the drama's four central performers. Last series I found that both Derek Jacobi and Anne Reid had taken somewhat of a backseat to their younger counterparts, however the opening episodes of series three have really put them back in the spotlight. Reid has been particularly good in bringing out the pricklier aspects of Celia's character and in particular her truly feelings about Caroline's sexuality. One of Reid's strengths is her ability to convey her emotions through a couple of facial expressions that allow the audience to know exactly what she's thinking. Though she's not been as prominent a presence as she was in series two, Nicola Walker has still been magnificent and showed a skill for comic timing during a particularly memorable scene in episode two. But so far this series has belonged to the excellent Sarah Lancashire who, as Caroline, has presented her frustration with Celia in a believable manner. Lancashire portrays Caroline as a formidable yet vulnerable woman whose cool exterior has started to melt thanks to her relationship with Kate. Ultimately, after a shaky start, it's great to have our Yorkshire friends back with us for a third series of Last Tango. Whilst I hope that Wainwright finds a way to reunite the characters once again, I feel that the actors are doing a great job of telling the writer's brilliantly constructed story and I for one hope the series runs and runs.

Radio Times review

There's a lovely opening to the third series of Sally Wainwright's warm, spiky drama as Alan tells Celia a funny shaggy-dog story over their Valentine's Day meal.

It's so typical of Wainwright, who has such a wonderful eye and ear for the little moments in relationships, the daft jokes and the shared humour. You'll be glad that she and Last Tango are back.

Alan and Celia (Derek Jacobi and Anne Reid) are settling into married life. But this story has never been just about them. Celia's daughter Caroline (Bafta-winner Sarah Lancashire) is settling into life with her beloved, pregnant Kate (Nina Sosanya). And Gillian (Nicola Walker), once so unhappy in that grim farm on the moor, has a date with a handsome man (played by Rupert Graves).

It's simply good to see everyone again, even though we know that this will never be, thank heavens, a story full of hearts and flowers. There are thorns, too.
