Argento.

Fulci is very close, but honestly, he made more than 90 films, the vast majority of which most of us haven't seen. Horror was something he stumbled upon late in his career. He was a horror director for a short period of time only. I love his films, it was close with Argento.

Romero is so overrated it isn't funny. He made three zombie flicks that, despite naff SFX and stupid painted blue faces, have survived. The rest of his work is pretty horrible. Every now and again he resurrects another zombie, and we get messes like Creepshow, Two Evil Eyes etc. Romero's "Night of the Living Dead" was excellent. However, looking at his career overall, he's pretty worthless, imo.

We all have our opinions.

I like Romero because of his style in alot of the films, and the certain messages that people usually don't see for some reason.
Racism is one.
Most commonly seen in his movies.


Oh, and they were grayish green in Day, lol.

Oh yeah, each to their own. I think his movies LACK style, to be honest. Most of them look like they could have been made by anyone. Subtexts, while interesting, don't alone make a great - or even a good - film. As a horror fan, Romero hasn't made anything significant to the genre for years. Now he desperately needs a hit, so he's going to wheel out another zombie film. Talk about last gasp.....

Well, he hasn't really been "Big and popular" even when the Romero movie craze was going on.

He does have somewhat of a style, it is weird how he writes his scripts.
He writes the theme first, and then adds characters later.
Which is a reason for people not to accept his work, so maybe one road block in his career.

But I think you might agree that he is a better film maker then Owe Boll(House of the Dead director)

Maybe.
I need to see more Argento films.

I have seen a few Fulci's but I still want to see Argento...
I saw DEEP RED, but I didn't like it much, but I still loved the music.
So I am going to take my chances with that other one of his movies that is really hard to spell.

Romero

But....Ive only seen 1 of his....and none of Fulci/Argento's....

I agree that Romero tries to express his take on society and it's faults/shortcomings in his films, this is one constant in most of his movies. As for gore you can't beat Fulci, City of the Living Dead and The Beyond are great examples. For me Argento concentrates on, "the story" staying true to it's theme throughout.

Being I can only pick one, I'm going with Romereo.

I like fulci's films.
and I dont think Fulci ever beat the scene in the lab in DAY OF THE DEAD.
When you first see Bub and the professor.
