People actually liked this movie?

Rating: 4/10 (14 October 2009)

What was it? The very deep teenager like plot? The bad acting? The plastic feel of everything you see in the movie? The melodramatic direction of the music? That the bad people are very bad, and the good people are very good?
Seriously, this movie is full of clichés and a predictable plot. It looks to me that JJ Abrams applied his TV philosophy to film... and that really doesn't work.
I would have enjoyed this movie when I was 15.... I really can't understand why it has an 8 and how it can be on the 250 top list of IMDb.
