Upon hindsight, the movie kinda gives off the "Save The Environment" vibe; half the time, they talk about humanity destroying the environment and we not doing anything to change [God knows how many times have I heard this word too!] for the better.
Then again, this isn't all science fiction either; in fact, the truth is also not that far away.
And yeah, this movie is what I would classify as "money well spent".
