my favorite part of Revenge of the Sith? That they CGI-ied Peter Cushing back so Christopher Lee could have his old co-star back in one last film at least. Its sad that he's gone, but holy crap, what a life to have lived. And I'm very, very glad that he got a late career appreciation/resuscitation as an awesome old guy. Also, despite his obvious declining health its incredible how he kept working as much as he could (his entire, brief part in Burke and Hare is performed while bed prone), whatta guy.
Also, if we're talking just pure, pound for pound filmmaking quality, there's a strong case to be made of the Lee Dracula series being the best horror film series ever.
