Very intriguing, on-edge movie. Great plot! When it ended, I thought, "OmG! I'm ready for part two!!" The best movie I've seen in years!! I cannot stop talking about it. The ending made clear a question I had earlier in the movie. Matt had destroyed the teleport machine in the first world when Jane went to his world to find out about him, and she was trying to get back. Therefore, it really seemed fit that since Matt had also killed the lab tech in the first world (Jane's world), there was no one to fix the machine. How could she have gotten through? She was definitely in the wrong world. But is it that there was another Matt as evil in the "wrong world" that Jane was in as the world Jane took Matt to (the world she belongs to)? I love that we have to be guessing, lol.
