What Halloween Movies Are Good For Young Kids?

I've got a 5 year old boy and a 9 year old girl and an itch to show them some of my favorite movies.  I've also, unfortunately got a conscience and an obligation to do my best to not traumatize my own children.

So, for the next few years, I will hold off on letting them watch the really gory stuff. House of 1000 Corpses will have to wait until the boy hits teenage years.  But for now, there's some good movies, right?  It doesn't ALL have to be Casper and Charlie Brown, does it?

Here's a couple Halloween movies I've come up with that I THINK I'm okay with showing the kids:

Gremlins is a no brainer, but that's a Christmas movie, and Ghostbusters is a year rounder so neither belongs on this list.

Hocus Pocus

Beetlejuice

Goosebumps

Is that it?  That CAN'T be it.  There has to be spooky movies that are worth watching while also not freaking the kids out.  Got any ideas?
