My wife and I went to this movie as a date night movie. We both enjoyed it - as a date night, it was a success.
It was an entertaining movie. I agree with the critics that the plot was predictable and the special effects were excellent. For a movie from the guy who gave us Terminator, Aliens, and Titanic, I would have been surprised if there was anything different in it.
I don't think the 3D was worth the extra money, the NASA trailer for the upcoming IMAX 3D movie on repairing the Hubble telescope took infinitely better advantage of the 3D capabilities.
