Well, the MST crew has done it again. This movie is extremely bad. The plot is weak and is very confusing. The special effects are even worse. Granted it was the 1950s and not nearly as advanced as today, but come on, they could have done better. Worst of all was the dub-bing. It has such terrible dialogue, that doesn't even make any sense. Of course, the movie makes for a classic episode of Mystery Science Theater 3000. So many hilarious lines come from Mike, Servo and Crow; I almost busted a gut from laughing. As with the many other terrible movies, avoid Prince of Space unless you have the protection of MST.
