I saw this film, too. I gave it a 7 out of 10. I enjoyed myself a bit more in this than Man of Steel (hey, summer movies, bitches....gonna be seeing almost all of them).
It some great acting, at times...surprisingly. At others, it felt like a rehearsal rather than the real deal. Just like my man, Patient Leech, shaky camera bullshit got annoying.
Some points were rather dumb...especially the very brief moments it did anything related to science. Obviously, a highschool student that pays attention will get irritated. However, most move goers (and people in general) are dumb.
The movie also cut around too quickly and too fast. I was able to follow it (all of us in this thread are movie buffs and can pick up on that stuff much more readily the the standard population) but I know my fellow movie theater goers were going, "huh? Why are they doing that? Why are they there, now? When did that change?" This is where the movie fails. You don't make a film for pundits of fiction...it just won't sell too well. You've gotta make a film like JJ Abrams: very easy stories to follow.
Maybe a small budget indie film can be made with hard to follow action...that stuff can be made for the critics and pundits.
But not a movie like this.
