The fact this spinoff from the TV series boasted the biggest UK box office opening weekend ever for a comedy film serves as testament to the power of small screen roots and loyal fan bases. One gets the feeling The Inbetweeners Movie attracted people to the cinema who wouldn't normally go, in the same way Philipa Lloyd's Mamma Mia! might have done in 2008. Large groups of friends hanging out in the Multiplex instead of Movida. If nothing else it proves that people are willing to go to the movies as much because of who they're going with than because of the draw of the film itself. Even the brilliant Community, currently on hiatus in the US, carries the hashtag on twitter #sixseasonsandamovie. Here though, if you're not familiar with the prurient antics of Will, Jay, Neil and Simon as they navigate their way through the teenage tundra, there's little to see here other than a never-ending stream of wee, poo, bum, tit, fanny, shag and cock gags that serve instead of a script. And yet, surprisingly, there's an honesty at heart too, much as I tried to ignore it; there's a kind of American Pie-like celebration of loser triumph over alpha male pageantry that's annoyingly feel-good, coupled with the deep, deep embarrassing recognition of some of the schoolboy-dicktalk that's all too familiar.
