The "Halloween Movie Series" Novels. Need input from Horror readers?

[AllHallowsEve]

I found novel versions of Halloween, Halloween 2, Halloween 3, and Halloween 4.

I was just wondering if the novels add anything that the movies didn't? If they directly follow the movies, I really wouldn't have the interest in reading them.

If they are like the old Simon Hawke Friday the 13th novels from the 80's which added backstory, additional scenes, and fleshed out the characters, I would be interested.

Basically, are they worth my time?

P.S. I am not talking about the young adult series with completely different stories. I read through a few pages and they didnt really interest me.

I've read Halloween 1 & 2 many times and they both add some backstory and definitely flesh out the characters, story and dialogue. I highly recommend reading them.
