I have seen R.L. Stine on the Goosebumps TV show, and I have read several of his popular books from the series of the same name. I would have to say that his writing has a pretty good way for scaring some people and keeping them guessing.
I have also read his autobiography and found out some interesting things about him and his books like how he came up with the Monster Blood books. Besides his writing all those Goosebumps books, he also did another book series I don't think I have ever read called Fear Street. Another TV show he did writing for is an old preschool series on Nickelodeon called Eureka's Castle. I remember taping that TV show when I was 8 years old.
All in all, RLS is an incredible writer.
