After seeing it last night i agree with pretty much everyone that it had a predictable plot. Still a good film, but too long for what it was (course it is James Cameron, so you expect that).
My first 3D film too and it was pretty amazing at times. Still not perfect, like it did blur and flicker a bit when people run fast across the screen. But the amount of depth it adds is crazy. Its a weird experience, after awhile i thought, this is how all films look, but then took the glasses off and seen how flat it was. Its a new, but also familiar experience if that makes sense. Like you can see everything already in 2D, say like a hallway down in the background, but in 3D it adds a lot of depth. Reminded me of playing a computer game or something. Hard to explain, needs to be seen, but a really good first time 3D film for me.
