When watching “ A Zombie Christmas Musical”, you would hope to have about a third of each for a good mix of a film. The 2017 film Anna and the Apocalypse is more of “A Musical with some Zombies that happens to take place at Christmas”, but that' isn’t necessarily a bad thing. Forget the comparisons to Shaun of the Dead and watch it as its own film and give us a listen. Or just give us a listen if you hate musicals, we promise Derek only sings a few times.
