Seing people rating this movie bigger than 5 proves that visuals are the only thing that matters for some people. Or this was the first movie they saw.

Visual there is nothing that anybody can say. The movie is a leap in CGI compare with the last one and years apart from any other movie.

The problem is the rest. James Cameron spends soo much time showing the world that you get in love or you want to leave (I'm in the second group). The dialogue was write using every cliché in cinema, and every action is drive by the stupid actions of the same character.

3h15 is too much for a movie that probably could be cut in 1h. None of the new character is better that previous movie and the old ones are there only for actions scenes.

Go to cinema for the visuals but drink a strong coffee before.
