I love the Lost Boys, although it's not one of got on DVD, one of my old flatmates had a copy, so it's something that needs to go on my "to buy" list! There's some very good music in that film,

I always thought that the more modern version of "The Thing" was closer to the original "Who Goes There" than the older B&W version. It's an interesting film, but the special effects were a bit cheesy in places, and even those who made them agree if you listen to the commentary on the DVD (which is worth doing, it's quite interesting).
One of the films which I thought was quite chilling was Poltergeist, although the sequels were a bit pants. Some of the moments in that film are eerie, and I'd think probably still are.
