Great visuals. Great acting. Some good science. Some ridiculous science. Very squirrelly ending. Matthew McConaughey is terrific. The movie kept my interest but I kept thinking I was watching a movie that was trying to do too much. Contact meets 2001: A Space Odyssey meets M. Night Shyamalan. I was fascinated by the concept of the movie...dying Earth and the decision to save humanity versus stay with your kids...but it just did not totally hang together for me. Toward the end of the movie the science gets shakier and shakier until the ending comes along and I felt cheated. I love Christopher Nolan's work. I just felt like this visually beautiful and well acted movie went on too long and then tied it all up way too neatly at the end.
