While I don't have much to say about the Underworld movies, I will respond to the bit about sequels. Most sequels tend to be... not so good. They're usually written just to cash in on the popularity of the first movie. While most actors don't really care and figure it's just easy money, some of them actually don't want to be known for that. To be honest, I wouldn't want to be associated with Terminator 3 or Speed 2 myself. I thought the third Fast and the Furious was better than the second. Anyways, a bit of info that might make your day -- Vin Diesel has been talking about doing the third XXX movie, and both him and Paul Walker are in the the new "Fast and Furious" movie. How's that for a confusing play on the name?
