JDelekto: I usually love anything with Zombies... however, that being said, I usually like to pick the better of the offerings out there (and there are a lot of stinkers out there trying to get in on the bandwagon).
- Night of the Living Dead (Romero)
- Dawn of the Dead (Both Romero original and Re-make)
- Day of the Dead (Romero)
- Land of the Dead (Romero)
- Diary of the Dead (Romero)
- Survival of the Dead (Romero)
- Zombi (Fulci)
- Zombi 2 (Fulci)
- Zombi 3 (Fulci)
- 28 Days Later
- 28 Weeks Later
- Flight of the Living Dead
- Resident Evil
- The Dead
- The Dead 2
- World War Z
- Re-Animator
- Dead-Alive (Early Peter Jackson, went under another title at one time)
- Return of the Living Dead
- Zombieland
- Shaun of the Dead
While in no particular order, I think that the original Romero "Dawn of the Dead" has to be one of my favorites.
Try "The Serpent and The Rainbow" (directed by Wes Craven) for a different kind of zombie movie.
