You can look at Joe Cornish's "Attack the Block" as the antithesis to Spielberg's ET. Instead of landing among nice middle-class California kids, Cornish places his alien invasion in what we in America would call projects: the kids swear, smoke and deal dope. There's a genuineness to the protagonists thanks to the fine script and the acting. You will marvel at these young actors, most of whom this was their first time in front of a camera. You care about these people, they aren't just plot point props. And the aliens are a CGI-less revelation with Cornish relying on old-school effects and it succeeds brilliantly. For example, the alien teeth glow in the dark and this is used to great effect -- when you see it, it's an ooo-that's-cool moment. This movie was Cornish's first and it is produced by his friend, Edgar Wright, and his influence is felt in the overall tone. I recommend this movie unreservedly, giving it five out of five stars. Seek this underappreciated movie out!
