I've been waiting since 2001, when the film version of Harry Potter and the Philosopher's Stone first came out, for the film series to come to an end -- so I could find out what all the hoopla was about. That is to say: sometime soon I intend to watch the first seven films in a marathon sitting, and then head out to the theaters for the final one.
I have absolutely no knowledge of the franchise, characters, story-line, etc. As you can imagine, steering clear of any and all spoilers during the last ten years has been an incredibly tough job.
If there are any other Harry Potter virgins out there, feel free to use my admission as a launching pad for your own.
