The Order of the Pheonix

My power went out and the day has been an odd one, but I did see Harry Potter and the Order of the Pheonix, the first movie I've seen in a theater in many months. I'm not going to do a full review. I just finished the book, and wanted to see the movie quickly so I can move on to the next. It's my least favorite of the books, though that's still high praise, and my least favorite of the movies, though that too is praise. So:

On the Shockwave Radio Theater scale of 9 to 23, where 9 is low and all SKZ Brust works get a 17, I'd rate Harry Potter and the Order of the Pheonix with these conditions:

If you've read the books and seen the previous movie: 17.

If you've seen the movies: 14.

If you haven't seen any of the movies or read any of the books: Don't bother going.

Non-spoiler non-comment: There is nothing after the credits.
