Dude, this book was REALLY strange. I don't know what to say about it, I finished this book a while ago but comprehending this book takes a while. So that's why I'm gonna rant about it. I enjoyed this book but it was odd, even compared to R. L. Stine's weirder works like "A Shocker on Shock Street" this was crazy. First off this was way more science fiction than horror (Which happens occasionally for Goosebumps.) Second, this book's story is so WEIRD it doesn't have much of the tropes for Goosebumps. Third, the Class of 1947 is still one of the scariest Goosebumps quote-on-quote villains. (Not because there scary (which they are) but because of how strange and uncanny they felt.) Final thoughts, this book is really odd but I do seriously believe it could become a classic book because I have never read something like it. (There are books similar to it but never children's books I feel.)
