It's hard to choose... I've got a soft spot for CITY OF THE LIVING DEAD because it was the first Fulci flick I watched. But then again, he's made so many great movies, that I have a really hard time choosing an all-time favorite. At the present though I'm really into DEMONIA, so I'll go with that one.
