First I'll admit that it has been a long time since the prospect of great special effects and brilliant action sequences was enough to get me to go to a movie. I'll also admit that Avatar had the best 3-D I've ever seen and the CGI was perfectly seamless. It is great looking.
But it is not even a good movie. No matter how terrific a movie looks, it still has to have an engaging story or at least interesting characters. Avatar has neither.
