This movie will appeal to most adults (and alot of teens) for is amazing and in depth storyline and wonderful use of special efx to ehance the plot and characters. James Cammeron vision was like watching a dreamscape unfold before you. The movie is long but it's length enhances the development of the characters and story. Sci.Fi.fans and fantasy fans will love it best. I have friends who have already seen this movie twice and plan on a third time. Also this is truly a "big screen" film. I can't imagine watching at home on DVD (especially the IMAX 3 D experience).
