The release date for the next Harry Potter movie has been pushed back to July 2009.
Normally this wouldn't bother me so much, but I finally got around to reading the entire series last summer (seven books in 14 days!), so I was kind of looking forward to seeing Half-Blood Prince in November. It will be the first Harry Potter movie I've seen where I already know what's going to happen before I walk into the theater.
I'm mad at you, Warner Bros.
