MONSTER A-GO-GO is the only movie, to date, that successfully put me to sleep. And yes, I was watching the MST3K version. It's a miracle Joel and the 'bots survived.
Remember when I once talked about the difference between movies that actually try to be good but wind up sucking anyway, and movies where the filmmakers simply don't give a crap at all? MONSTER A-GO-GO is one of the latter. Just horrific.
