Whats this movie similar to?

Well, I wouldn't say that Laymon's books are better than King's. They were nothing too deep; just light, breezy reading. And the majority of his novels have to do with psychotic killers. It wasn't often when he wrote horror stories that had to do with the supernatural or monsters. Mainly his stories involved some deranged lunatic. It's like reading an early-80s slasher story, only much more graphic. That's the other thing, too, some of his books were downright nasty; just loaded with explicit gore and violence, and an occasional brutal rape. I would classify Laymon's books as "pulp horror fiction".

The reason his books have been ignored by the movie studios is probably because of his lack of popularity in America. But you never know, some producer may decide that the time is ripe for a Richard Laymon novel to become a movie, especially when you consider the kind of brutal horror movies they make these days.

By the way, I think that Funland may have indeed been inspired by the Tobe Hooper movie because the story is about certain horrors that occur at a local carnival.
