The first three movies in that series were amazing. After that, it got a little weird and stale. But the hare krishna zombie in Dawn of the Dead, and the self-aware Bub in Day of the Dead ... dang, great filmmaking.
I haven't seen any confirmation that the location in a recent issue of The Walking Dead is a nod to Romero, but it would make sense for Kirkman to do it. Kirkman was a fan of Romero's.
