This film is a masterpiece. The Planet doesn't shy away from the real issue at hand, unlike so many other films of this nature. Without giving too much away, this film is very balanced; not overly optimistic, yet not too pessimistic either. Also strikingly different from other movies of the sort is how many cultures are explored, from first world countries to developing nations. Yet, it never loses the focus of the message presented early on in the film--that we have a time frame in which we must act in order to prevent further, more severe consequences than have already appeared.
That being said, the cinematography in this film is exceptional. The scenes were gorgeously shot, and the careful editing really captures the scale of the issue, from the smallest insects to the entire globe. Perhaps most noticeable is how well the soundtrack (of a very electronic nature) flows with the visuals. There is one scene that combines the music with the scene (you'll know it when you see it) so well I would have purchased a ticket to see it alone.
The Planet is not to be missed.
