The riffs in the MST3K version were spot-on and at times, fall-over hilarious; these riffs in the Rifftrax Live version fall flat, although a few are funny. (Why couldn't they have stuck with the original riffs?) I also don't like when they do the picture-in-picture effect showing the guys in panels next to the film as they riff; it takes away from the humor. Still, the film transfer looks better here and more colorful, and includes the full version of the movie as opposed to MST3K's edited version (although most of the extra scenes drag out the movie a bit and don't contribute much). All in all, I'll stick with the MST3K version for maximum laughs.
