I couldn't believe Avatar was as long as it apparently was - I was ready for more! The computer graphics, 3-D and sound effects were stunning, especially on the IMAX screen. The graphic characters' acting was warm and believable, unlike some previous 3-D efforts like Polar Express. The human acting was fine, except for the one-dimensional baddies. The story was pretty predictable, but Cameron made it all so visually captivating, you didn't really mind. Absolutely a must-see!
