The first act is a bit meh, folk horror stuff, coming-of-age stuff, some decent zombie bits but once Jodie Comer gets some room and Ralph Fiennes' great performance brings a bit of unhinged madness, the skys the limit. There's some mildly annoying plot holes but its a zombie movie ffs. Some great performances, a slighly clunky script but the last few minutes are the icing on a long-awaited cake. Good fun with some decent emotive scenes.
