"Up" is nothing if not a garden of delights. This is the kind of movie that Hollywood used to do so well.
I'm going to plant a flag and say that the fourth film in the "Terminator" series is not science fiction. Furthermore, that's exactly its problem.
This is going to be only half a review of "Angels and Demons" - because I could only make it through the first half of the film.
These couples FLOAT. I don't think I can better describe this phenomenon without diminishing it. If you've taken that walk even once, count yourself fortunate.
