The movie does suffer a little through actors who vaguely look like bigger name actors but aren't. Of course you have Dave Franco, playing his brother James Franco as someone who dies far earlier than expected. Then you have the male lead, Nicholas Hoult as Zac Efron as Broody Zombie. Finally there's Teresa Palmer as Kristen Stewart as Actually Likable. The funny thing is, these actors all do a better job than I'd expect their doppelgangers would.
The film has a great unique way of telling the story through a perspective you never see, while still being relatable through common themes and human emotions. While it's not much of a comedy there are plenty of great jokes and moments, Rob Corddry commonly breaking character to provide many of them. The soundtrack is excellent containing plenty of original scores that heighten action and emotion and great licensed songs at lighter moments. The visuals and effects are equally as impressive, even if the Bonies feel a little copy-pasted sometimes.
Before I get any hate, I still firmly denounce the ridiculous notion that love can cure zombies.
