Episode 2 had some cringeworthy moments but that's great, of course, if you're a Number 9 fan.
It's even better if you're a fan of Psychoville: in fact, it's likely that a great many fans of Psychoville forgot entirely that they were watching an episode of Inside Number 9.
Even the most "normal" of viewers chancing upon this episode by pure accident while flicking through channels would have found the dancing scenes remarkably funny. It also has to be said that this episode has what is possibly the funniest and cleverest line of narration I've ever heard. It was beautifully underplayed and it wouldn't surprise me if quite a few viewers didn't get the joke.
As ever, commendably weird and wonderful entertainment from two of the most talented comedy writers/actors of our generation.
