This movie was so, so good! Of course there are always going to be things that I think could have been done better, but overall, they did a great job. I will say though, that one thing that really bothered me was how they always keep the people's original voices when they take polyjuice potion. It makes the whole reason for taking polyjuice obsolete! If someone keeps trying to talk to you and you don't answer because they'll hear your own voice, they'll obviously know something is wrong, and your cover is blown.

One thing that I thought would have been cool to do was to have scenes showing what was going on at Hogwarts. There's never enough Snape in any of the movies. I think it would have been especially cool if they would have shown Neville, Luna, and Ginny breaking into Snape's office to get Gryffindor's sword and then getting caught by Snape.
