You can follow this link to watch parts of the show on YouTube. (I can’t embed code on my blog right now, so you’ll just have to follow the links).
I’ve only watched the first three parts, but I already love how they’re playing with the characters’ personalities to tease out some of the funnier parts of the books. I think they’re doing sort of a mish-mash of all the books, which actually works pretty well.
And the part about foreshadowing? Totally awesome!
UPDATE: Sadly, the students responsible for the show had to pull the entire thing off YouTube because they were worried about copyright lawsuits. Personally, I think they are protected because the show is a parody, but I’m no legal expert. You can watch an explanation of their choice (and a great new song by the kid who plays Harry Potter) as you wait for the soundtrack.
