I'll probably see this, but I still don't really like the idea of re-riffing films featured on MST3K. There's other movies to riff, plus the MANOS episode is one of Joel's best. I could understand re-riffing from the KTMA season.
If this is true, they need to at least two great shorts, and the complete uncut version of MANOS. I donèt know what was cut from MST3K, if any footage.
