I didn't know anything about the movie going in, heard only about the hype - ended up being pleasantly surprised. We did see the movie in IMAX 3D, but ended up in the very front row so THAT experience is not worth sharing. Nonetheless, the special effects were outstanding, the Avatars were "real" and the storyline, although somewhat predictable, was strong enough to bring a tear to my eye. Would love to see this again from the rear of the theater this time. Took my boys, ages 11 and 13, and both enjoyed with no complaints about the length of the film.
