->''You may come from beyond the moon,\\
But to me, you're just a goon!''
-->--'''The Other Three''', lyrics to TitleThemeTune "Monster A Go-Go!"

->''I recall this episode as being the first time we decided explicitly to write sketches having nothing to do with the movie. Really, we had no choice. (...A)ny topic that is about something (that is, any topic that exhibits "topicness") cannot, by definition, have anything to do with this movie.''
-->--'''Paul Chaplin''', ''The {{Mystery Science Theater 3000}} Amazing Colossal Episode Guide''

Director Herschell Gordon Lewis needed another movie to round out a double-feature with ''Moonshine Mountain''. So he bought Bill Rebane’s unfinished "Terror at Halfday," added a couple of extra scenes, some new dialogue, some narration, ''nothing else'', and ''voilà'': "''Monster A Go-Go!''", a half finished stinker!

When describing this movie, the word "why" inexplicably comes up a lot. Why does Dr. Logan protect the monster that killed his brother, Dr. Logan? Why do we never hear anything further from all the characters that lost friends and family to the monster? Why does it seem that the narrator is watching a completely different movie? Why can't I hear anything? ''WHY DOES THIS MOVIE EXIST?''

When ''MysteryScienceTheater3000'' played this movie, they crew agreed that it was the worst they'd seen to that point. When watching ''ManosTheHandsOfFate'', this movie is mentioned as being worse. With ''Manos'', one can at least say that Torgo is a saving grace for that movie -- but ''this'' movie has no such grace. It's ''bad''. '''Real''' '''''bad'''''. [[Comicbook/{{Doom}} A 12.0 on the 10.0 scale of badness]], and [[SoBadItsHorrible not in a good way.]]

!!This film provides examples of:

* BlatantLies - anything the narrator says.
* ContemplateOurNavels
* CosmicHorror - ...maybe?
* DullSurprise - Rumors that this movie had actors turned out to be greatly exaggerated.
* DreadfulMusician - The composer of the actual score.
-->'''[[MysteryScienceTheater3000 Joel]]:''' ''What is this, Chinese Music Torture!?''
* DidNotDoTheResearch - Nothing works anything like this movie portrays it. Except, perhaps, the utter boredom of nothing in particular happening.
* {{Fainting}}
* GainaxEnding - [[spoiler:There was no monster.]]
* InfoDump
* LastNameBasis - The Logan brothers.
* JerkAss - Dr. Carl. Talks about how well a mission went when ''the pilot didn't come back alive'', instructs a mother not to tell her son that his step-father is dead, and inexplicably disappears before doing anything useful.
*{{Leitmotif}}
* MindScrew - Not because of symbolism, so much as complete incompetence combined with the fact that the film has nothing approaching even the incoherence of chaos.
* NotableOriginalMusic
* ParodyRetcon: H.G. Lewis claimed this movie was a parody of some sort, instead of a half-assed crime against cinema.
* TheScream
* ShockingSwerve
* SoBadItsHorrible
* SpaceClothes - On the monster. Inexplicably.
* SpecialEffectFailure
-->'''Narrator:''' ''Surely, this was the space capsule Douglas flew out on.''
-->'''[[MysteryScienceTheater3000 Tom Servo]]:''' [laughing] ''Douglas was pear shaped, very short, and stood the whole way!''
** And of course, the infamous scene where the sound of a phone ringing was clearly made by ''someone offscreen mimicking it''. This can be hard to catch, but ''MST3K'' calls it out:
--->'''Joel''': ''...unbelievable.''
--->'''General''': [answers phone] ''Yes?''
--->'''Tom Servo''': [as general] ''Yes, I made that phone noise.''
* StockFootage - The film would have been made out of scotch tape and Popsicle sticks, but they broke the budget.
* TitleThemeTune
* TheTreacheryOfImages - the ending.
* UnreliableNarrator
* TheUnintelligible
* WallBanger - Even as bad as this movie is, the ending ''[[BeyondTheImpossible still sticks out as being particularly awful]]''. [[http://www.agonybooth.com/recaps/Monster_A_Go_Go_1965.aspx In the words]] of Agony Booth's Albert Walker:
--> Words simply fail me here. There is no way to communicate how much this ending completely and utterly sucks.
* WhatHappenedToTheMouse - About half the characters disappear about halfway into the movie.
