BRICK

Movie review in one paragraph:

Film noir set in the 00s, with technicolor and high school kids speaking like exact counterparts of their 30s and 40s ancestral characters (the girl victim, the detective with the brainy sidekick, the Kingpin, the diva with her lapdog, the cunniving woman, the mindless muscle and the crazy snitch - you most certainly will need an urban dictionary), undecided yet whether it's hilarious, or intriguingly mysterious, but certainly worth a watch.

Out on DVD for Region 1 and 2, a new (as of 19th October) theatre release in Greece (only Athens' screenings for the time being). Official site HERE.
