This is a eye-popping movie that absolutely must be seen in IMAX to be appreciated. It shares a lot with Cameron's other epic, Titanic, in that the plot is a little hackneyed, and you know what is coming from the beginning. Also like Titanic, since you know what's coming, at some point you wish the movie would just get on with it rather than spend more than 45 minutes going into character development and subplots. Otherwise, though, the movie was entertaining, and the special effects are mind-blowing. The feeling of immersion with IMAX was not to be missed.
