Science: completely implausible Plot: dull, tedious Acting: wooden Best scene: when Cooper is saying goodbye to his daughter and his wristwatch jumps back from 9.02 to 8.20 This film is possible entertainment for the feeble-minded. Overall, overwhelming disappointment considering the lengthy positive reviews written by supposedly intelligent people. Why waste so much energy. A shame it is digital because if the movie was on celluloid at least it would burn well. Not a patch on 2001. This film doesn't deserve 10 lines of review. I have stated my case precisely and it would be pointless to add anything. This movie is about an hour too long.
