Klepto platypus? You mean a niffler?
I'm more a fan of the books than the movies. After Chamber of Secrets, although I watched the movies, I just couldn't get over how much more clever the stories were in the books.
But I'm highly looking forward to seeing this flick. There's not a book that tells this story more clever than the movie, because I don't think this story has been told yet (unless I missed something on Pottermore or similar). I must add to my knowledge of the Harry Potter canon, even if the villain has weak character development.
Now, what'd I do with my giant nerd pin?
