I think Van Helsing wins the award for absolute, never-stopping-never-ending-constant-action-galore. I liked the movie's action and effects (I LOVE the coach chase and the Wolf Man Vs. Dracula final battle), but there was little character development and a million plot holes. Also, Roxburg as Dracula was painfully over-the-top terrible.
But anyway, this movie has action practically every 5 or 10 minutes. Jam-Packed.
