The worst movie that appeared on mst3k?

Worst one I've seen so far would have been Invasion of the Neptune Men. Although the moment when they blew up the Hitler Building was priceless.

Manos was hilarious. I loved Torgo and how he snuck up on people and felt their hair, lol. The worst movie would probably have to be Lazerblast. It was just absurd. Aliens came and killed a monster with a giant laser crafted to his hand. Then, a teenage boy came along and found the laser and starts wreaking havoc. From that point on, it's just 70 minutes of a whiny teenager making things explode.

It is really tough to pick just one...there are so many. Speaking of plots, The Starfighters didn't have anything, just briefings and flights. However, I cannot point to that episode and wish they hadn't done it, because of the "Poopy Suit" song.

The worst movie is definitely the Starfighters one. Lack of plot (or no plot at all) and unnecessary characters (and I do mean ALL of them).
