Do you have any idea how hard it is to be a charming zombie? Think about it: You see a hot girl. Let's call her Julie (Take Me Home Tonight's Teresa Palmer). She's smart, funny and knows her way around an assault rifle.
How are you going to sweep her off her feet when: A) You can barely speak, B) You reek of decomp, and C) You're technically trying to kill each other?
For Nicholas Hoult's R (his character can't remember his whole name), the trick is to rescue the damsel from the other walking dead, then show her his cool record collection.
The fact that any of this works is thanks to the film's light, funny take on Isaac Marion's novel of the same name, and the delight that is Hoult.
