Visually, the movie is absolutely beautiful. However much they spent on the visual effects was well spent. The movie makes an excellent screen saver and/or ambient lighting if you turn off the sound.

But aside from that... The script is fairly terrible, the acting is relatively fair, and the screenplay is uneven and uninspired. The plot is essentially the same as the first 'Avatar', but you don't really care about any of the characters this time around. The requisite battle scenes are there and they are, of course, majestic. Lots of whooping and hissing.

The movie is weighed down by what amounts to about two hours of filler: it's Avatars being pretty Avatars. There are many, MANY lengthy segments that don't feel like they have anything to do with the plot; They make you feel like you are watching a nature documentary with killer special effects.

Formulaic and predictable, but definitely pretty to look at. But there is absolutely no reason this movie needed to be over 3 hours long.
