I quite enjoy Halloween III personally, it's the only one apart from the first one I have ever bothered to rewatch. Fun, weird, creepy little effort. Loved the head pulling scene.
I just recently watched it. I like it on its own. It's got a great soundtrack, too. Plus a good amount of meta humor - love when you see the ad for the original Halloween on the TV screen when Challis is in the bar. It's like it's confirming, "No, Michael Myers will NOT be seen anywhere in this movie!"
