Just perfect.

Rating: 9/10 (29 December 2009)

Why I say that? Let's see:
First the story was simple. No big twists, no million story-lines, no needless happenings. No too much love and no incompetent characters. No cool heroes, no bitch-like girls for show. And no airy, flippant characters for bringing boring jokes and making the movie awkward.
Second the CGI is masterful and it is through the entire movie not just for some big scenes. From the first leaf to the last water drop, all exist. When a plane crashing to the trees, when the birds flying over the water, it really happens, you don't feel it's just CGI. Amazing.
The clichés? Well, there are elements in the movie we already saw in other movies, but who cares? We already saw Titanic before Cameron's version, and we saw movies about prisoners before Shawshank Redemption. If somebody shots a good photo of a sunset, nobody should shot sunsets ever more? I don't care about clichés when they are in perfect balance with the other components of the movie.
Overall, this movie is well balanced with good characters, a unique CGI and unique way it brings the well known message about protecting your environment. (10 is for perfect not just excellent.)
