Good!

I collect Point Horror books, and as obviously R.L. Stine isn't the only author to write Point Horror, I know a particularly better author when I see (read?) one.
Babysitter is a very good book. The whole series is good. Usually when there is more than one book it gets boring, but not this series. There is a twist in the tale, and when you find out why things happen, it's weird because it's totally unexpected! Mind you, for people with a more vivid imagination, like me, you put your own twist on things too!!
Stine's writing style is good. It's relaxed and easy to take in, you don't have to read a sentence three times to understand it, like you do with some more complicated books.
