This movie was such a disappointment.
The visuals are stunning, the music is great, and I was looking forward to being introduced to the new water world.
The story is a bad patch up of every bad war movie you've ever seen mixed with Rambo, Jaws and Free Willy, just to show off the visuals it feels like. No real introduction except for explosions, rushing between places, jumping whales, TONS of weapons with endless ammunition, seemingly endless fight scenes, hardly any meaningful dialogue all over. I know Cameron is not the most creative when it comes to storytelling (looking at you Avatar 1 or should I say...Pocahontas!), but this was just beyond lazy. There is no heart to the story, it's rushed all over the place, doesn't make sense half of the time (others have pointed out mistakes already) but the deal breaker for me was the character development.
Jake Sully, former marine, hardheaded as they come, fiercely independent, is now a cowering, "Let's just go and hide!" father who doesn't know basic military training anymore (taking a tracking sensor back to your hideout, aye?). His wife, an equally independent and fierce soul, is now standing behind Jake at all times, begrudgingly following him around and seemingly having lost her spirit most of the time. The kids can hardly be told apart, wondering why they had to have so many when only 2 really had a story to follow.
The money and the storylines were wasted on this. This should have been two or three movies. By the final fight, I was hoping it
would be over soon.
