The first hour does a good job with the "people are the real zombie apocalypse" ground that The Walking Dead would later cover again and again and again, but it's pretty slow, and I don't think the performances really carry it.
The idea of educating a zombie is pretty interesting.
There's some pretty awesome gore in the last third, if you like that sort of thing. I still liked the two earlier Romero zombie films better.
The score had me singing the similar-sounding Journey song "Who's Crying Now?"
