Yeah it is stunning, but 5 minutes looking at how they are swimming....and such things...you can comfortably skip to the last half hour and the last fight.

They spend most of the movie showing how they are adapting to the water and being under and then in the end, all of the sudden it looks like they are afraid to be in the water, like they can't snorkle and hold their breaths for a couple of minutes LOL And where do the sea people disappear all of the sudden in the middle of the fight?!?

Lots of plot holes.

I found myself wondering after the end, if I will be able to make myself watch another one of this avatar movies once it is finished....shame.
