Okay here is the scoop. This was an unfinished movie that a few added scenes and was edited together almost at random, so it could be used as part of a double feature. That is why everything is all screwed up, that and the initial inept directing, crappy acting and other such.
Monster A Go Go, it sound like the name of a bad camp movie, but it's really the name of a bad, bad, bad, bad, bad, bad horror movie. It is the worst movie ever made. The reason most MSTies say Manos is worst is because it's a more popular episode because Joel & the bots could make fun of it more. This however was too hard to make fun of. In the MST3K book (Amazing Colossal Episode Guide) they note this was the first time in a while that they didn't do any host segments related to the movie, because NOTHING happens. Manos, had intriguing characters like Torgo, The Master, and hell even Debbie. This has Henry Hite with some mud on his face for two shots.
Only see this movie on Mystery Science Theater 3000. Even then it isn't that good as they don't really have anything to work with.
