I will probably have to pass on the Riddick movie. I wasn't all that impressed with "Pitch Black" or whatever the film was to introduce the Riddick character to the big screen. And this one just hasn't impressed me from the trailers.
I, too, saw "The Day After Tomorrow" and would say it was pretty good, allthings considered. The whole story is a bit extreme, but I can buy into that, but there are some parts of the story that are just absolutely cheesey as hell. But I go to movies to be entertained, and I thought it was entertaining.
