This movie was nothing more then a video game on a grand scale. Camerons pathetic use of Sigourney Weaver was critical to remind us of an 'alien' thing going on. This for me was his'Titanic'.I recommend it after you take a couple of hits from your teens (or your own) stash. Good men does a movie make, not computers. Mr. Cameron leave the computer stuff to Pixar for our grand-children.
