Given the title there is a real lack of gorilla stories in this collection, which may disappoint gorilla aficionados. With around 60+ short stories, there is literally only 2 gorilla stories, 12 pages out of 620.
But, this is a science fiction collection, and there is plenty going on here that is worth checking out. Featuring tales from strange adventures, mystery in space and action comics, you have some wildly inventive sci-fi tales to keep you entertained. Some highlights include the continuous adventures of Tommy tomorrow, who is given top billing with his head on the spine of the cover, and also captain comet. You also get some recurring characters like Bert Branson, investigator for interplanetary insurance inc, which might just be the real star of this anthology compilation.
Most stories are entertaining, but as with any anthology compilation, you do get some duds, some stories can be too technical and science heavy, or feel a little "samey" this is the type of book, not to read continuously, but to dip in whilst reading something else, purely because these stories are short, mostly self contained, but they can still be dense reads, which is no bad thing in general.
So I highly recommend this, it's entertaining, gives a nice snapshot of th 50s science fiction era, and they're breezy light reads(some maybe dense, but at 4-6pages they can still be read fairly quick). But as mentioned if you are interested because you expect a planet of the apes gorilla world themed set of stories, you need to look elsewhere I'm afraid.
