It was a good movie. Plenty of laughs. A few fart jokes and potty humor, which is mindless comedy. I guess I have been spoiled by Pixar movies and think that every animated movie should live up to Pixar's quality, but this one does not. It's good enough, overall.
THE MOVIE WAS GREAT! There, I said it. Many people will p00-p00 parts of the movie, or the movie in whole, but I don't care what you think, this is about what I think. The acting is getting better as the movies go on. The kids have learned to be more "angsty teen" and "adult" at the same time. Draco Malfoy has really come into his own in that respect, but then he has always been a side character without many lines on the whole.
So, after all is said and done, I think this is the best movie so far in the series. I have a lot more on my blog, but this place wont let me link it.
