We saw Avatar on a regular screen when it opened and over the weekend saw it on an IMAX screen in 32. It was really cool. I'd recommend 3D for anyone who hasn't been yet. I loved the movie. Great special effects. You forget you're watching computer-generated figures. They're so expressive.
Fun Movie. Way cool on an IMAX screen. Loved all the actors, great story, super special effects, fun touches of humor, and little references to past Star Trek movies and TV series. See it!
