Hate to say this, being a huge Romero fan for the last 25 or so years (especially his zombie movies), but I've just got back from seeing this & was sorely disappointed.
I wish this was George parodying his own work, but fear it was not. It started out taking a little swipe at today's horror movies, only to fall foul to their mistakes as well. I know the film is low budget, but I expected better - the 'acting' is poor, the plot a mess & the attempts at humour (mostly) fail.
There were even a couple of moments where I had my head in my hands thinking 'You've got to be kidding me!'.
Some people will probably kid themselves that the overall cheesiness was deliberate, but I don't think you could honestly beleive that - no matter how big a Romero fan you are.
On a (semi) plus point - there are some nice effects (especially one right at the very end), but also too much CGI. Bring back the prosthetics & condoms filled with fake blood!!
