After hearing my buddy Richard reluctantly telling me how good this film was I knew I had to see it. I highly recommend this film, in 3D if possible. The 3D isn't kitschy here, it only adds to the immersive experience. The visuals are stunning. I'm not a big fan of excessive CGI and this movie has a lot of CGI. But it is convincing, you are in an alien environment. I saw Cameron's IMAX The Deep and so I was not expecting Cameron to do CGI well - I was wrong. It was amazing!
The story is simple, but that works. The environment is an amazing rich character in this film - so having a huge complex story would just be overwhelming. Just because the story is straight forward do not assume there is no depth here. I should say that story is classic and allows Cameron to explore deep themes in this film. The obvious theme is one of cultural domination that is rooted in the ignorance of the dominating species. But there is so much more in this theme. The ecological themes actually take a similar track - and turn back on the humans as a indictment against our own despoiling of our planet.
