So I forgot to mention I watched mother fucking Avatar. 3D but not imax (a mistake, I think).
It was pretty fucking awesome, even though it has some cheesy ass shit in it. The world is pretty well developed, the creatures and plants and environment, and the human stuff, too. It is a movie with a message, but its so brutally obvious what the message is almost immediately, that it doesn't really bother you (well, at least not me). The 3D effects are really fucking cool, except when a foreground element is blurred, that is actually very irritating. Anyway, its a great cinema experience, even if you don't like the plot, you'll probably find some way to enjoy this film.
