Let's be realistic.

Boring

A lot of perfectly good film show their cards early, establish a unique premise and let the audience explore a topic at a leisurely pace, without much in terms of surprise. this film is not one of those films.

True to its essence, the characters remain on the same line and manage to entertain the viewer, each highlighting their own distinctive qualities or touches.

Good. Gravy. Some of the notoriously bad movies I leave feeling almost robbed, since I find at least one worthwhile thing. Manos was inept on every level, but the story was at least an idea (note that I didn't say a good one). Zombie Nightmare at least had Adam West and Tia Carrere in it. Reefer Madness and Batman & Robin I find too silly to get really angry about. Monster a-Go Go... I've got nothing.This is first time I've gotten headaches and nausea from the cinematography alone. Not anything displayed on screen, the camera- work by itself was enough to make me sick. As if that weren't enough, every frame looks like the negative was photocopied 17 times and spliced together, the sound and dialogue made me think my ear buds had gone dead, and the concept itself makes no sense. Given that the project had been abandoned in 1961, then picked up, finished, and put out in 1965, it should come as a surprise to no one that the story is borderline incomprehensible - I'm talking trying to divide by zero while drunkenly stumbling through a hedge maze levels of confounded here. Of course, that's not even close to the biggest problem with the movie: the ending. Not since Robot Monster have I seen such a cop- out conclusion for a movie so mind- bogglingly lazy, out-of-place, nonsensical, and insulting to the audience.This thing is the current title holder for the worst movie ever made, in my own opinion. If there comes a film to dethrone it, I will retract this statement accordingly. However, I am convinced that it would have to consist of two hours of TV static with a cat hacking up in the background while a monkey takes a tire iron to my skull for me to even slightly consider it for my bottom spot, and even then it likely still wouldn't be as bad as Monster a-Go Go.

This is one of world's worst films ever made - or so some say but I have seen worse.. so much worse than 'Monster A Go Go'. This film is not great at all but it is entertaining but drab at the same time. This is not a film I would recommend to anyone although I found it kinda neat in a way. This is an 'ok' bad b-film - not good but certainly not the worst.The film reminds me of a fairly good home movie... as if some inspiring filmmakers and actors made it. It has it's moments of being fun and interesting but I will admit it is a bit dry.If you really want to watch a drab but kinda entertaining bad b-film then you might like 'Monster A Go Go' - otherwise you can easily pass on this flick because you won't miss anything by not watching it.3/10

Indeed, this movie is the worst of the worst. Worst than "Manos: The Hands of Fate", worst than "Birdemic: Shock and Terror", even worst than "In Search of the Titanic". I cant really talk about the plot, because you can barely even see/hear anything in this movie.In matter of fact, Joel Hodgson of Mystery Science Theater 3000 said this is the worst movie he's ever seen. Also, there's the monster. It just looks like some guy that they covered up in band aids and slapped some make up on him. So, if you want to mentally scar yourself, I recommend Monster a- Go Go.My rating: 1/10

I watched the MST3K version of this movie, and I don't think I could have watched the original version. This was just too boring & confusing of a movie to watch without someone making fun of it. The audio was atrocious and it was hard to make out what the actors were saying, not to mention that some of the sound effects were way too loud for the action (which made not only Joel & the bots jump, but me as well). The one scene were the guy goes "brrring" before he answers the phone is priceless. I suspect they meant to overdub a ringing phone sound effect at that point but forgot to. The tiny space capsule was also quite laughable.The ending, though, is totally anticlimactic, pointless, and confusing. Two men in radiation suits are chasing the monster through the sewers when all of a sudden it disappears, and a telegram arrives saying that the missing astronaut was found safe & sound in the Atlantic Ocean. We're supposed to be left pondering whether or not the monster was the astronaut and how the monster disappeared the moment the astronaut was found. But it rather gives the impression that they didn't really have an ending for the movie and hurriedly wrote one.Overall, this is one of the worst movies of all time and deserves its spot in the bottom 100.
