I've just seen it today.....and I absolutely loved it.
I'd seen this thread title before I left to go to the cinemas and thought "great, that's encouraging" however I genuinely think this was the best HP film so far. The opening was a bit "meh" and really pointless, however since it was relatively short i'll not dwell too much on it. The Hermione/Ron romance was touching, IMO. I think alot of HP fans who HAVEN'T read the books were probably suspecting Harry + Hermione to get together. Slughorn was fantastic and really convincing. Young Tom Riddle was superb, as was Lavendar Brown and Luna Lovegood.
The only thing that annoys me about all the HP films are that nothing ever seems to be explained properly at the end. Speaking as someone who has read all the books it's not that big deal, however I can imagine plenty of HP fans were probably left feeling a bit confused at the Half Blood Prince thing (which added nothing to the film), the necklace (I think Dumbledore mumbled the explanation for this at the end, however it wasn't very clear at all) and the Romilda Vane/Cormac McLaggen characters (who seemed to just be "there" because they were in the book).
The Good -
Luna Lovegood, Bellatrix Lestrange, Draco Malfoy, Severus Snape, Lavendar Brown, Slughorn and Tom Riddle were all fantastic.
Hermione and Ron were superb as usual, and their story was a relaxing side point from the darkness of the Horcruxes.
The duels looked alot more realistic.
The cave scene was well done.
The scene with Dumbledore's body and the students raising their wanRAB was a nice touch.
Although a bit pointless, the Burrow scene was exciting and really demonstrated the horror and violence that the Death Eaters were capable of.
An entertaining film overall which was a nice teaser for Deathly Hallows.
The Bad -
No Madam Rosmerta.
No Dursleys.
No Dobby (although I can't remember if he was in the book?)
Dissapointing ending with a very short battle scene.
Not enough Hagrid.
Dragged on a bit.
The HBP story was essentially pointless and added nothing to the film.
Not enough Tonks or Lupin (I mean, ONE scene??)
No mention of Sirius.
