This review is written by a huge zombie movie fan.

The musical format simply didn't work. The musics are not even very well connected to the plot and very few of the "jokes" are actually funny. While the technical aspects such as photography and make-up are neither impressive nor terrible, the average-to-bad acting, amateur-like plot, and musics that make you wish the finish quickly make this movie a waste of time to most of people.

I would say that you should watch it only if you love both musical-comedy and zombie movies, and still this is not going to be a super good movie for you.
