In terms of the overall series or franchise, I'd agree with the consensus that the Batman movies have had the best villains, and as bad as Ross Webster, Gus Gorman, Ross Webster's sister (I wanna say Vera?), and Nuclear Man were, and although the comic egotistical career criminal that is Gene Hackman's Lex Luthor doesn't do much for me, I'd have to say the superhero movie series that's had the worst or lamest villains is Ghost Rider. I've almost completely forgotten who the villain in Spirit of Vengeance even was. Beyond Batman, the X-Men, Spider-Man, and Superman, I can really only speak to the rogues galleries of the various superhero movies, because in most of these cases, I haven't read enough - I'm not too familiar with the rogues galleries of Iron Man, The Fantastic Four, or, well, Ghost Rider, for instance.
