Glaswegian comedian Frankie Boyle's controversial interjections on Mock The Week turned that show into must-see TV for many, and his loss made the show immediately less infamous. There's certainly a place for Boyle's brand of "shock comedy" on network television, particularly in a landscape currently dominated by family-friendly comics like Michael McIntyre, Rhod Gilbert and John Bishop. Sadly, Frankie Boyle's Tramadol Nights is a horrendous mess, on the evidence of its first episode.

It uses a tried-and-trusted format: stand-up comedy interspersed with sketches. What's unfortunate is that (a) Boyle's stand-up routines are taken directly from his recent tour, meaning many fans will have heard the jokes before, and (b) the sketches were idiotic attempts at shocking people that dragged on past their natural end points. The first sketch, running with the idea that David Hasselhoff's character in Knight Rider was mentally ill, was perhaps the worst offender - a target 25 years out of date, a stupid idea you'd expect from a schoolboy, producing a sketch that seemed to last forever. Other sketches included candid camera spoof "Hide Me, I've Killed A Kid", an animated "George Michael's Highway Code" (topical?) and a bizarre parody of The Green Mile where the black character's supernatural power came from... raping people?

Tramadol Nights was objectionable in a way it wasn't aiming for; a show with zero intelligence behind it. I could scarcely believe Frankie Boyle's the bearded ringmaster of this tripe, as the prospect of a Channel 4 comedy from him was a delicious prospect up until last night. Too much of its sketches were pale excuses for Boyle to visually enact jokes that work better in the minds of an audience being told them verbally. At the very least, someone should have reminded Boyle that a sketch works best if it's less than two-minutes long, not twice that.

The sole positive: you don't need to buy Frankie Boyle's DVD as a stocking filler this Christmas, because it seems likely all of its material will be served up here each week.
