Hurt Locker is well written, engages the viewer, but much of the movie, especially the end, are a little fantastic. As long as you remember that it is a movie, not a documentary, you will enjoy it.
Thanks... sounds pretty good, although I've heard from some vets that there's not a lot of accuracy in the film.
What's your opinon of Avatar? I hope to see it just for the CGI special effects, but heard all about the stupid uber-left plot.
