I would say I didn't go out of my way to see it. But, I really ended up enjoying it, despite some of the things which seem to be commonly brought to attention.
I got a lot of recycled plot elements out of it, but, in all honesty, if they could be taken as a whole, they form a pretty nifty original plot. If anything, I regret that movies with inferior plots hadn't used similar plot elements. The ends justified the means, in my opinion.
After watching the movie, though, I felt kind of melancholy. I didn't just feel bad for the movie characters, but humanity in its current state, as well. Consider the setup: this wicked awesome fantasy forest planet with cool tribal cat people gets invaded by sky people half their size.
The humans made jackasses of themselves, so they were banished. This left me wondering if the humans, on their way back to earth, would consider an easier way of life, less dominated by gadgets and paperwork, or if they called it a day and went on to bother some other planet.
But, the world view of the native cat people was also irreversibly changed. In a sense, all Nietzsche-like, the sky people killed earth god. When the home tree went down, their god didn't seem omnipotent. Even if they beat the sky people this time, how long is it going to be before the sky people bring back more than their god can ward off?
Then, I felt bad walking out of the movie theater, along the pavement, towards my gas consumption burden, finishing my soda, realizing that it is highly unlikely that I will see humanity accomplish worth a damn (consider that my standards are not mere feats of practical science) in my life time.
Anyways, I'm glad someone started this thread so I didn't have to. And for anyone who's feeling skeptical about seeing it: put yourself out of your own misery and watch the f***ing movie.
