The first minute of this movie really lighted the fire: Flying together with the Deatheaters caused me feel like car-sick, and the collaps of the Millennium Bridge also brought some "Armageddon" feelings. But then the director seemed to recall the idea, and put the boys and girls back in the school, making the whole thing more like a high school movie. BTW I really don't like the arrangement of the love relationship among our main roles: Ron is too fat for Hermione, and Ginny is just too normal for Harry. I would rather make a H&H couple, and assign Ron back to his bitchy GF. Guess what? I also wanna add some spicy things here by making Drako and Ginny a "Romeo & Juliet" couple! Seriously, why didn't Rowling never think about that?
The later half of the movie made almost all of my friends sleepy, and no exception for me. If the whole thing is about some evil plot, it's obviously not that evil or complicated that we really need our brain cell to digest.
The new professor Jim Broadbent（as Horace）is average, but the mad woman Helena Bonham Carter (as Bellatrix) really drove me mad. There are some "formulas" to play a bad guy in a movie, but she definitely did not get it.
Finally, may the soul of Dumbledore rest in peace...
