Avatar was a great movie, but the 3D made everything look blurry and out-of-focus. This made it difficult to see the finer details of James Cameron's incredible CGI. Furthermore, whenever there was rapid movement onscreen (such as during the final battle) all I could make out were a bunch of colorful, fast-moving blobs. Personally, I'm planning on seeing Avatar again in 2D so I can truly enjoy it. I can't recommend watching it in 3D.
