Thanks Torgaman, I'll have to listen to the examples you pointed out.  While we're at it, this thread seems as good a place as any to ask for other lucha libre/horror recommendations.  Outside of the Santo movies, it doesn't seem like there are many that are English-friendly with either subs or dubs.  What am I missing from Mil Mascaras, Blue Demon, Superzan, Neutron and the rest of them?
