I saw Avatar in San Franciso on a regular, big screen over the holidays and it blew my socks off. I saw it again a month later in Michigan on IMAX /3D. Since I knew the story, I enjoyed the effects all the more. The colors are saturated and there is a graceful elegance of movement throughout the movie. In another month, I'll probably go again. The DVD will never be able to replace the big screen enjoyment.
