Overall this was my least favorite of the books though with that said it is still far and above just about every other book I have ever read!
I was very disappointed to see Sirius die. Though he never did become the pleasant character that I wanted him to - I just couldn't stand the fact that once Harry had someone to call family that he lost him - How much sorrow can one kid stand!
I also didn't like the fact that Harry was in in a horrible mood for most of the book - though as others have mentioned this is pretty much par for the age and probably appropriate.
I missed some of the light-heartedness that was in the first three and a half books - but again I understand why they are going this direction - it's just sad I guess.
I'm also a little disappointed to see that it appears we are leading up to the major battle between Harry and Vol being the end of book seven. I know that's predictable, but I have always liked that these books were a little unpredictable so I hope I am wrong and she twists that up some way.
I missed that Hagrid and Dumbledore weren't more front and center and Dumbledore's avoidance of Harry really bothered me.
i thought it was cool that the prophecy had been made by Trelawney and that explained why Dumbldore kept her around.
I am glad Harry didn't end up with Cho - I don't think he has met the girl for him yet unless it turns out to be Ginny so he can officially become apart of the Weasley family.
I loved Fred and George's whole storyline and I hope that we somehow see more of them in the last two books.
I loved that Neville started to come into his own.
I don't understand why Dumbledore chosse Malfoy to be a prefect.... Can you imagine if he became Head Boy? (opposite Hermione, obviously) And I think he is going to play some major role in the final showdown also, but I haven't decided yet which side he is going to be on - I am not so sure it will be evil...... I think he is this generations Snape and we know that Snape turns to the good....so.......
ok enough rambling
