Me too

They both had that oddball reputation, and I thought they had a lovely relationship in the books - I mean Harry never made fun of her (as her so called frienRAB did

) Luna always seemed to get to the heart of the matter with Harry. I think Harry/Luna would have been more interesting than Harry/Ginny, which was always a little cliche.
Thought the actress who played Luna was fantastic, and Tom Felton was excellent as well. Both really stood out. Really liked Harry when he was drunk on the lucky potion. I'm not normally impressed with Dan, but thought he played a blinder in those scenes. I was laughing like a loon.
Agree with the posters who were disappointed that crucial elements to HBP and points necessary for DH were missed out - thought TPTB made really bad choices in what to include. I know they can't include everything, but no Gaunts, Bill getting bitten by the werewolfs, no Dursleys or protection spells but enough time for Harry to be flirting badly in a random cafe
I'd give it a 6/10 mainly for Draco's plot line, Molly Weasley's face when she was watching her home burn (only highlight in another useless added scene),Slughorn and Luna.
