I like it. It was entertaining, weird in a good way and funny. Not really the typical zombie, I used to watch in movies, TV shows or even books. ( Like Resident Evil, Walking Dead and the only zombie book, well not totally a zombie story but a guide, The Zombie Survival Guide: Complete Protection from the Living Dead or maybe zombie books like World War Z) 
 R is a zombie, but he is changing when he met and save Julie from other zombies. He actually feels, just like humans and in that way, he is becoming human. It's weird that a zombie can fall in love with a human. Sweet yet weird. I wonder what is his real name... probably Romeo? Julie is Juliette? 
 I don't know, maybe I'll just wait for the sequel somehow he'll regain his memory and I hope it's better. 
 As for the movie, Nicholas Hoult did a good job as R. He did really looked like a zombie, better than the book's description. It's funny and I can't help smiling inside the movie house.
