See the pattern in my reviews of late? I've gone from a straightforward zombie movie to a semi-comedic one to an even less serious, if not more comedic, one. I'd been putting this off not simply because of the subgenre and some, eheh, lukewarm reviews but because the trailer seemed to give away everything. But maybe seven years after watching that trailer once, I could find it fresh enough.
The premises herein deviate from the norm to the point that "zombie" is almost misleading. Well into an outbreak, the protagonist (Nicholas Hoult) is a young adult shambler who can remember no more about his past life than his first initial, R, but still retains some semblance of personality for the nonce, as by collecting and playing vinyl records in a plane he inhabits alone. He feels bad about eating people, tho not so bad that he'd rather starve to a more complete death, and he dreads the day he'll embrace this identity in full. Also, eating brains both prevents the rise of a new zombie and allows him access to the memories contained therein. But apparently even before doing that to a certain Perry (Dave Franco), he takes a special interest in Perry's girlfriend, Julie (Teresa Palmer), and impulsively decides to help her survive. By and by, Julie can't help, y'know, warming up to him too.
