1/5 Oh, the horror of it all!
  by Robert Holmes Weymouth
I purchased this movie almost one year ago and I have watched it twice at most. Despite the director and musical score master of Gojira, their job on this one was a task too great even for their "genius"(?)
Three monsters derived from earth creatures descend upon some researchers and islanders and take what seems like forever to attack and then only one at a time. The giant cuttlefish is the most likeable of the beasts and he bows out first. That is the only spoiler I will throw in to this review. Overall, the one star I gave it should be a zero.

3/5 3 INTERESTING MONSTERS. 1 UNINTERESTING MOVIE
  by JACK LOBO (Greenwich,CT USA)
Okay now, just what kind of movie is Space Amoeba? The opening is very similar to the opening of Ghidrah The Three Headed Monster. Gezora the walking squid, Ganime the furry crab, and Kameaba the elongated turtle are engaged in a three-way battle during the opening credits. Unfortunately this battle never occurrs in the movie itself. The best way to let you know what this movie is like is to do this; Remove King Kong, Godzilla, and any cool city destruction scenes from King Kong vs Godzilla, but keep Fero Island, the natives, and the giant octopus. Then remove Godzilla, the secret military base, and air-strike attack from Godzilla vs Ebirah (the Sea Monster). Finally, remove all the major monsters, city destruction, and space aliens that you can see from Destroy All Monsters, and keep only one lesser known monster. Put it altogether and you pretty much have Space Ameoba. I love a lot of Akira Ifukube's music especially the big over the top energetic stuff, or the signature motifs he puts to certain monsters. He gets lots of kudos for scoring this movie, but I thought it was very weak and lacking in the intensity Mr Ifukube has put into other films. Now for the dvd itself. Audio has English mono and 5.1, Japanese mono and 5.1, and an audio commentary spoken in Japanese. Subtitles are Eng 1, Eng 2, and Eng 3. Eng 1 shows nothing for me. Eng 2 displays what I suspect to be what the Japanese actors were really saying because it's often very different from the english dub. Eng 3 subtitles are for you to read the commentary. Well there you have it, Space Amoeba. AKA Yog, Monster From Space, AKA Gezora, Ganime, and Kameaba: Decisive Battle.

4/5 Splendidly cheesy kaiju!

OK, it's not Seven Samurai. It's not Gojira. But it's a fun romp through the world of giant rubber-suit Japanese monsters. Best served with chips or popcorn.

5/5 Space Amoeba- A Great Monster Movie
  by Ellen R. Fissel (South Mountain, PA USA)
Space Amoeba is a great sci-fi monster movie. It is better than most people think it is. The monsters are different than those you would normally see, but thats a good thing.

The acting is good, the monsters are well designed (especially Kameba, the turtle). The movie has a lot of action for a kaiju film and it keeps the viewer interested.

This movie is worth the price! Buy this movie and enjoy it again and again! A great monster movie for a great price.

3/5 YES ! THIS IS THE LONG LOST 'YOG MONSTER FROM SPACE'!

I had not seen this movie since I was a kid and I was really amazed I came across this on Amazon under the title 'Space Amoeba' which was the original title released in Japan. This is another silly outing from the Toho studios during their hey day! I can't resist these goofy films from my youth, even though they are silly with hilarious FX. They do bring us "Godzilla/Toho" fans back to a simpler time, when all you needed was a creepy flick on TV(Creature Features,Chiller Theater) and a few plastic army men to keep you happy. I spent many hours in the lobby of the local theater during Matinees recreating the fight scenes with my friends and destroying popcorn boxes etc. LOL! Aaahhh...the good ol' days! The DVD treatment is very good here but, too bad most of it is in Japanese.....At least they give us sub-titles to understand what they are talking about. The film itself is presented in widescreen with English or Japanese audio and option sub-titles. The DVD transfer is better than most of these Toho films have seen...anyway I'm glad I have it!...it was a fun trip back in time!
