I felt it was done well, though I would have liked to have seen more with the actual Order of the Phoenix. The fight between Voldemort & Dumbledore was exactly as I'd pictured it in the book. Luna Lovegood is far more endearing than I expected (I thought she'd just be annoying, but really that title went to Cho). The special effects were excellent. Given this was my least favourite book, I can't wait for more!
Confession time...Daniel Radcliffe (Harry) is just far too good looking & has far too nice of a body for a boy so young.
