First off, 10/10 for visual effects.
Right, i watched this movie in 3D, i took off my glasses once or twice during it to see what it was like in 2D and really, it looked fine too. I'm sure this is better in 3D but i've seen 3D films before and this is nothing new.
Anyway the movie starts of ok, though its seeminly set in a future where humans forgot how to make bullet proof glass and jets, and instead decided to replace it with lots and lots of hornets from halo 3. Anyway we're introduced to jake sully who, after rescuing batman at the end of termimator 4, seems to have ended up in a wheelchair. He gets a big blue avatar to control so he can guard ripley and her team of big blue avatars. He's also given a secret mission by generic bad guy military man.
After somehow failing to hit a massive 20ft panther dog thing with more than 3 bullets, he gets split up from ripley and co and gets rescued by pochahontas. 2 hours later, after watching a film that is almost an exact replica of pochahontas plot wise (seriously, there's even an angry fiancé and a talking tree) it finally gets into a battle scene that has just a bit more screen time than venom does in spiderman 3.
You have to wonder why the hornets dont have bullet proof glass. That's a super design flaw there. And if they're making so much money from erm, unobtainium, you think they'd be able to afford jets.
In conclusion it looked fantastic but the pochahontas story and the incredibly dull characters dragged it down. It just felt too long.
4, maybe 5, out of 10.
