"You've never heard of the flying mountains of Pandora?" In the year 2154, humans have begun to exploit places beyond Earth, the latest being the moon Pandora for its rich unobtanium deposits. Since the Pandoran atmosphere is toxic, this is partially done through avatars, a fusion of human DNA with that of the native Na'vi. Naturally, the natives do not appreciate their home being encroached upon by outsiders.
This movie cost at least $237 million to make. So far, it has grossed $1.6 billion, putting it $200 million shy of becoming the top grossing film of all time. The plot's essentially the same as Pocahontas, Fern Gully, Dances with Wolves, or anything else in a similar vein. Give it the Academy Award for Best Special Effects (because it's 2 hours and 45 minutes of stunning visuals), but it's nothing to write home about beyond that. I could also go into the aspects of the film I found unrealistic (continuity issues with the Na'vi weapons, language in the 2150s being identical to our own, etc), but that can be tossed aside as the "fiction" aspect of "science fiction."
I recently got around to watching The Hangover for the first time, and found it similarly underwhelming.
