it may not be the PERFECT action movie but then again it might be. If you don't like action movies you'll still probably like it because it's so well made. Remarkably for Cameron it has a lot of heart and is actually ABOUT something. Personally I don't think anyone should not see it. And BTW it really is all it's cracked up to be in terms of revolutionizing the film viewing (and film making for the un-budget-restrained too I'm sure) experience.
This movie was SO freaking boring and stupid that people were walking out of the screening. I'd rather be forced to sit through Transformers 2 again. THAT'S how pitifully bad this thing is. There's not one character or single line of dialogue in the picture that's not the lamest, most obvious or just totally uninteresting. And the visuals... if you like the SAME SHOT over and over, like when a car drives through crumbling buildings, then a plane flies through them, then another plane does the exact same thing again. Lame times 1000.
