Harry Potter and the Deathly Hallows: Part I (2010) is a dark and intense movie. It is sometimes exciting and other times slow and somber. There is an awful lot of scenes where people are running away from terrible things. There is also at least one scene too many of people sitting around sad and wondering what they should do next. Still, I was never bored, but the under-13 crowd might find this movie slow and depressing.
This is more of an adult Harry Potter, unlike the first movie 9 years ago where all the main characters were young children. Here they all look like young adults and they have some serious adult problems. Some people I know have made a fuss about a nude love scene, but that scene is a brief mirage strategically obscured by smoke. Nevertheless, this is clearly not a kiddie picture anymoe.
I think that the cinematography, special effects and attention to detail are the best we have seen so far in this series. The movie is a little too complicated to fully understand in one sitting, but that is O.K. It gives me reason to see it again.
P.S. I forgot to mention that there is much humor in the first half. The second half gets all serious and forgets about humor.
