Let me start stating something you already know for some time: I am quite stupid. Yeah. I needed to read in a comment to relate the two main characters to Romeo (named R in Warm Bodies) and Juliet (named Julie).
Well, regarding the movie, and although it is classified as a comedy I disagree. Romance, yes, it is. Horror not really, but I can understand why. Action, yeah, why not. And Drama, please. Well if in the last movie I’ve watched true love is the key to nymphomaniac cure, in Warm Bodies, love is the key to zombie cure. But if you think a little, any dead guy would rise in the sight of Teresa Palmer. So, no news there :-D
