First of all, I would just say that people shouldn't jump on the band wagon.
The special effects in the film were amazing yes, but thats what you get for being the most expensive film ever made, and I believe it took 14 years to make.
The storyline however, was awful. The funniest thing was in a trailer before the film, there was basically a cartoonised version of the film coming out, with humans attacking a planet of worm things that had to fend them off their planet.
I read, in America some people tried to commit suicide after watching Avatar, because they couldnt handle our planet not being like Pandora, thats the kind of immersement you get out of this film, you get sucked right in, until the end, especially with the 3D effects, although the 3D wasnt used to full advantage, it was used to show off more of the scenery than any action sequences sadly.
All in all, a thrilling 3-3 1/2 hours, should have got more oscars, as the hurt locker was just an awful film.
