The CGI was excellent, the romantic story was cute, but the anti-US/anti-corporate (in search of Unobtanium-- Unatainable goals--get it) and the tree hugging became overbearing. Be nice to mother earth and respect our resources... we get it! And although the IMAX experience was awesome, there really was not a lot of 3D "wow" moments. The story did not need them, and quite frankly the NASA trailer before the movie utilized the effect much better. A ground breaking movie that was interesting, but best movie? The jury is still out.
