I like happy endings (depending on the genre); I just don't like the movie telling me something is a happy ending when it really isn't. There's still a major issue to be dealt with at the end of MR (rampant murder), and they have no plan of how to deal with it. I suppose the argument could be that culture has changed so that murder is less of an issue, but I have a hard time buying that when they're about to release thousands of "murderers" onto the streets.
