In the first 20 minutes this movie tries too hard (way too hard) to be cool and hip, feeling like a very sloppy copy of a Tarantino movie. Then it becomes quite interesting and pretty enjoyable. BUT, here the last 40 minutes or so come, completely ruining it all with the introduction of that moronic Billy Lee character and a huge stepping down in tone that makes the movie feel like a teenage flick. Unbearable. Other than the inherent stupidness of his character, I think Chris Hemsworth also was a huge miscast.
