Although I have seen several IMAX films, they were all documentary types at museums. AVATAR seems custom made for this format. The plot/storyline were a little lame - think Fern Gully - but you hardly noticed, because the visuals are amazing!!! I spent the entire 2.5 hours completely still in my seat, fully immersed in Avatar's world. I can't say enough about the IMAX 3D. I have never had a movie experience this good. This is not a movie to wait for the DVD release. See Avatar in IMAX today!
