Production quality was good and all, but there was one fundamental thing that I didn't like - the zombies start thinking, communicating, and conspiring.  Totally stupid.  There were also a few things that the zombies did that were super lame.  I'd point some out but don't want to ruin anything.
Well if you go back to Day of the Dead they started thinking and trying to communicate and one of them used a gun.
I agree that it wasn't one of Romero's best. But I enjoyed it.
