Should DOTD 2004 even be called a remake?

Rating: Null/10 (10 April 2004)

Do you think this film could be even called a 'remake'? I saw the original again a few days before seeing Dawn of the Dead 2004, and the only similarity between them seemed to be the mall. Unless I've missed something. I don't think the two films should be compared, or that people should argue which one was better... because they're both entirely different.
Maybe the makers of DOTD 2004 only used the same name because they didn't to be later accused of plagiarism, after people saw that it took place in a mall?
Anyone have any thoughts?
