Despite the fact that Highlander fans deny the existence of all but the first film, the third with the sorcerer guy is almost as good (so good, Spoony didn't tear it apart like the others) as the original (continuity problems aside), the 4th with the TV show's characters was ok, and the Quickening is cheesy enough to be entertaining (with Michael Ironside and Sean Connery hamming it up). The Source, though, well let's just say that, unless you like watching an albino reverse-Pyramid Head make lame one liners and ham it up, it's incredibly dull.
Underworld is also a guilty pleasure. I'm still hoping they made the 3rd sequel to at least wrap up the "broken masquerade" and other plot lines the third introduced.
I also liked what already was mentioned: Starship Troopers, Judge Dredd, Shoot 'Em Up, Tremors, Fifth Element
Sucker Punch, They could have been more honest in the trailers. That might have been what hurt it commercially.
Alien 3, I still feel betrayed after how great Aliens was and after reading much better scripts, but it's at least servicable as a stand alone scifi film.
Alien Resurection, While we still didn't get the Aliens sequel we wanted, this campfest was at least as close as we might ever get with all the executed meddling the Alien franchise has crawling over it.

No, it was the distant past on planet Earth. Sorry, my inner Highlander fan jumped out there.
