I'm glad I read the positive reviews that caused me to give this movie a chance. It's not great in that the acting is mediocre, but the whole time travel beurocracy part and everyone's motivations made sense by the end of the movie, so that all worked for me. The movie also had some nice touches in it ghat I appreciated, like the assistants working through tv sets, the watches that beep when the time travelers are getting too close to doing something that woould adversely effect the future, and the bad guys in long coats and cowboy hats moving in slow motion. I also enjoyed the happy ending. Both I and my wife were glad we watched.
