I have to disagree I think there's a HUGE selection of vintage horror. I think AMC owns the rights to virtually all the Universals but at least we get Invisible Ray and Old Dark House.

Sadly we don't get the Haunted Palace, my personal Holy Grail of horror collecting! Anyone want to trade my soul for a copy? Or a story involving Ted Newsom, a large mocca latte, an elephant and six weeks in the desert? (Cudos to anyone who gets my reference)
