Fulci Masterpiece?

What is Fulci's masterpiece? City Of The Living Dead? Zombie? Don't Torture A Duckling? The House By The Cemetery? Conquest? Okay, probably not Conquest. Does he have more than one masterpiece? 

Godzilla

Not necessarily in prep for the new film, but I'm about to go Godzilla crazy. For real this time.

Giant man? Tiny Godzilla? You tell me.

I remember bits and pieces of Godzilla films on cable from my childhood. I don't remember really watching a whole film. (Although I did have a Godzilla action figure.) As a genre junkie (read: crazy person) I'm ready to give the kaiju genre a proper look. As an adult the only Godzilla film I've seen is Invasion Of The Astro Monster which I enjoyed. I did see the 1998 film and I did hate it. Oh and Godzilla wished me a happy 35th birthday. It was a highlight. Thanks Elizabeth!

I did pick up a bluray of Godzilla Vs. King Ghidorah and Godzilla Vs. Mothra both in one set in prep for a Godzilla Day next weekend. Or two days of Godzilla depending on how it goes. The purpose of this post is to pose a question: What Godzilla films do I need to see? Hit me up in the comments with your suggestions. If you have any!

Question

Today's question is short and sweet. What was the last great Italian Horror film? Hit me up in the comments.
