Its probably advisable to watch this film whilst under some kind of intoxicant, because its a crazy, crazy film that is perfect for stoners. Dont let that put you off though if that's not your thing: provided you can keep up with the pace then youre in for a good time whatever youre doing. Starring a pre-Hunger Games, but still adorable, Josh Hutcherson, and Shanley Caswell, who you may recognise from The Conjuring and Snow White: A Deadly Summer (you probably havent seen that one, but its worth pointing out), Detention begins like any classic slasher. The most popular girl in school gets bumped off (after a truly hilarious opening sequence) by somebody dressed as Cinderhella, a fictional serial killer from a popular slasher series within the film. We then see life from the schools second biggest loser (the biggest loser is a girl who performed oral sex on the school mascot, a giant stuffed bear), and, as youd expect from an American high school, its not pretty. After this fairly standard - but very well done - opening, things start to get a little bit strange in the best way. Someones part-fly (as in, the insect) and theres a surprising amount of time travel, which altogether makes for a seriously enjoyable frenetic rollercoaster of a film. If Scream was the postmodern reboot of the slasher genre, then Detention is a post-postmodern masterpiece of self-aware, anything-goes horror-comedy.
