Zombie query

So, I’ve actually gotten into the whole zombie-movie thing lately. I’ve sat down to watch Quarantine, Night of the Living Dead, both versions of Dawn of the Dead, 28 Days Later and 28 Weeks Later. I’ve recently seen The Omega Man and I Am Legend and Day of the Dead, not to mention the spooky French movie They Came Back (Les Revenants). Now I’m opening the floor up for suggestions. This is a rich and complex genre. It is both the last genre where pure, unspeakable horror is possible, and, paradoxically, the genre most capable of making broad statements about civilization and its fragility. That is, it is both the dumbest and smartest of genres. I haven’t ventured very far outside of acknowledged classics, and barely at all into the realm of low-budget exploitation (the closest I’ve come to that is Robert Rodriguez’s gonzo tribute Planet Terror). I saw one Robert Fulci* (*I mean Lucio Fulci, obviously) movie a long time ago, but otherwise have not seen a foreign language zombie movie and wouldn’t know where to start. I ask my strong-stomached readers to recommend their favorites.
