I've been hearing almost nothing but good about this movie and am very eager to see it, especially in IMAX 3D. I've heard it's just an amazing technological achievement. It also made 27 million in it's first day. I know other films made almost that in midnight shows but considering this is a sci-fi film with almost no big name stars and isn't a sequel or coming from a well established franchise, that's pretty damn good. I'd like to keep this thread spoiler free, unless marked of course. Please, post your thoughts on it here. Also if you can please specify if you saw it in 2D, 3D or IMAX 3D.
