When i first saw R (even with the zombie make-up) I thought "Oh my god, he is so cute." And then at the end I was like "Nevermind cute. HE'S HOT!" XD Very well done movie. Pretty good acting and fun characters. One to remember.
Also, there is a book? I haven't done much research on the movie yet (I don't have time for it so I won't get too excited about it until I have more time). I'd love to read that too! I'm looking it up as soon as I post this.
