Never read the books, but followed all the movies (only on DVD). Can't lie that the Harry Potter series of movies is indeed one for the books (unlike the pretentious one that tagged itself a saga and also did a 2 part movie of the last book.). I'm not a fan but watching the trailer of the last film made me excited to see it on the silver screen. Check it out yourself.
Ok... but I won't lie that I love Hermo... Emma Watson.
and... shut up... you probably got excited watching the Eclipse trailer.
