The film’s choice of incorporating music proved unsuccessful. The songs don't really fit with what's happening in the story, and most of the attempts at humor just fall flat. Although the cinematography and special effects makeup aren't particularly outstanding or awful, the performances are generally underwhelming, the storyline feels unrefined, and the musical numbers make you eager for it to be over, ultimately making this a disappointing experience for many viewers. I’d suggest watching it only if you have a strong appreciation for both musicals and zombie films; even then, don't expect much enjoyment from it.
