There were only a few loose similarities to the original film such as: A character named Capt. Rhodes, another named Sarah, and the Zombie du jour... 1985 "Bub"... in 2008... "Bud". Bud the vegetarian, he doesn't like human flesh! I have yet to see a Zombie chew the crap out of a head of lettuce.. Bud, who loves Cpl Sarah. Bud should have been drooling over everyone in that Hummer. Even the original "BUB" had limited expression. BUD acted more like a child, not a Zombie.
If there was no reference to Romero's version, this would be a great zombie flick. It had the "Zombie Nouveau" style like 28 Days Later as well as a few classic "moaning shufflers" in the mix. Because of the title "George A. Romero's Day of the Dead" it was a disappointment.
The upside... it had plenty of moments the kept you watching. Plus the "Black Satire" of the Horror Genre from the character Salazar is worth the watch. Let a friend watch this with you, but don't tell them what it is, if they are a fan of the Genre they will enjoy this movie. You tell them what it is... watch the disappointment flow.
