Oh, meant to say that I finally saw HP: ORDER OF THE PHOENIX over the weekend, and really liked it. I thought it actually worked better than the book (whitefonted just in case). So much of what annyoed me with OotP (Harry AND Sirius being miserable sulking shits, Umbridge, Dumbledore avoiding Harry, the Occulmency lessons) either worked on screen (Umbridge was an AWSOME villian in the movie) or was toned down (Sirius seeming more reckless and on Harry's side than petulant and bored).
The only thing I really thought missing or over-compressed (unless "Weasley is our king" was excised, which I cannot for the life of me remember which book it's in) was Snape's worst day memory, which was curtailed a bit too much (along with his antagonism towards Sirius which was completely gone). Also, I somehow missed how Harry knew that Snape was in the Order. Snape definitely is getting the short straw in the series, which is too bad because they've got the perfrect actor for it.
Destroying the hidden room is going to be a logistical problem come HALLOWS - maybe Hogwarts can heal itself or some such flebotenum.
All in all, I thought PoA was a better directed movie, but I thought the compressions and deletions in OotP were much less problematic. Also, the fight at the end rocked more than I remember it from the book (much as Cedric's death in GoF felt more important in the movie than I remember it from the book). Hope they keep this trend up - the last three have been really good, IMHO.
