The effects were great.
Tho, i didnt like the woman who played Bellatrix, i always thought of her as more of a crazy, sexy, bit worn out, woman. Didnt do justice for me. Dan Radcliff's acting had improved, but the scene where he was possessed wasnt that good. Cheesy voice, cheesy acting at that bit.
All in all tho, it was a big improvement. GoF sucked, it skipped too many chapters. But this was good.
I recommend anyone to see it
"We're not among the living, so we cannot die; but neither are we dead. For too long I have been parched with thirst but unable to quench it. Too long have I been starving to death, but have not died. I feel nothing; not the wind on my face nor the spray of the sea. Nor the warmth of a woman's flesh."
