Many prior reviews have implied predictability is a flaw for this movie. I agree this movie is a predictable socioeconomic and ecology driven love story. This is not a flaw, the movie is not about what is going to happen as it is about how it will happen. The effects are dazzling and the performances better than I expected. James Cameron has done it again and this is probably his best. One bit of advice, see it as many times as you can on the big screen because the DVD will never play as well at home.
