Jon Lucas and Scott Moore hit a goldmine when they wrote the script for The Hangover. It turns out young people like to watch movies where the characters on screen are partying so much that they’ll even buy tickets to retreads like The Hangover Part II, or movies that barely even qualify as being movies, like Project X. It’s gotten to the point where party-gone-out-of-control is pretty much a genre onto itself. Enter Lucas and Moore’s new film, which they’ve both written and directed, 21 & Over. Jeff Chang is newly turned 21, and despite the fact that he has an important interview tomorrow morning, a couple of his crazy friends have decided to take it upon themselves to take him out drinking and give him the night of his life. The results are a derivative mix of those aforementioned party films, a little bit of the journey aspect of the Harold & Kumar films, and a sprinkling of the way they kept repeating the name McLovin in Superbad (though here it’s repetition of the protagonist, Jeff Chang’s, name, Jeff Chang).
