Sometimes, Paul, we are way too much alike! I'm a total zombie freak.
Shaun of the Dead
Flight of the Living Dead
The Vanguard (very different)
Fido (a decent comedy)
Of course, I'm hardcore into the classics. I think I have every Romero film, and I have to pop in one of the Night of the Living Dead versions ocassionally (the 80's version had some nice twists on the original theme). I even like putting on the old red and blue 3-d glasses and watching the most recent "Night...". Worth the headache once in a while.
Land of the Dead and Diary of the Dead were both pretty good. I recently watched Survival of the Dead-actually wasn't impressed.
28 Weeks Later was a much better movie (IMO) than 28 Days.
I've also got a pretty good collection of low budget films, from the 1950's to the present.
One to look for is "Flesh Eater". Not a great movie by anyone's standards, but notable for the fact that it was written, directed and produced by Bill Hinzman (who also starred in it). Hinzman was the original Zombie in "NIght of the Living Dead". The special features are also disgusting and hilarious.
