Now, there were remakes for George A. Romero's "Dead" trilogy, including two(?) remakes for Night of the Living Dead, of which I have neither seen, Dawn of the Dead, a VERY good remake directed by a first-time director, Zack Snyder, but I know for sure, that this remake of Day of the Dead just lacked enough creativity than its predecessors, or some other zombie films.
Now referring to the original versions, Night of the Living Dead was certainly creative, and it became a cult classic, Dawn of the Dead was a stunning sequel, I haven't seen Day of the Dead, but hear it's not as good than the first two.
This remake, was just a plain movie that did not have anything unique throughout.
But looking on the positive side, half of the actors were great, such as Ving Rhames, although some negative feedback for Nick Cannon, I personally thought he did great and was humorous.
Appropriately, this remake is bad, don't buy it, just rent it with friends and watch it at night, you will likely have fun with it.
