I take it Sky is not an MST3K fan.

Personally I think there was a lot of talent put into that show, and rifftrax does a decent job of carrying on that tradition. Though I must admit, crappy movies make for much funnier riffs than good ones. Which I think is one reason I don't find rifftrax nearly as funny as MST3K. Most the movies rifftrax does are typical hollywood regurgitation, none of it very good, but none of it even close to half as bad as films like Overdrawn at the Memory Bank, or Mano: Hands of Fate.
