It’s been five years since Mystery Science Theater 3000 writer/host Mike Nelson parlayed that show’s cancellation into the downloadable-commentary online mainstay Rifftrax, during which time Nelson and frequent co-snarkers Kevin Murphy and Bill Corbett have transitioned from riffing on the sort of D-movie fare that was MST3K’s bread and butter to handily ripping apart blockbusters like Twilight, Harry Potter, Transformers, and much more.
