Harry Potter and the Deathly Hallows: Part 1 is an all right movie, just like its predecessor. It is exceedingly and unnecessarily confusing for people who haven't read the books, even if you have struggled to keep up with the movies. (I have not even done that, as I just now realized that I have never seen the third, fourth, or fifth movie.) Unlike its predecessor, however, there is finally some content and plot progression. Even though the plot is mind-numbing, it piqued my interest enough for me to read up on characters' backstories on Wikipedia for a good 1-2 hours after the movie. Perhaps one reason I found the plot to be so lackluster is that I've seen it all before--only better--in a little fantasy series entitled The Lord of the Rings. Harry Potter seems to have borrowed so extensively from that franchise, in fact, that it also picked up the same plodding pace and heavy atmosphere.
The movie has more than its fair share of flaws. The mood seemed to jump from terrifying horror to child-like comedy at the drop of a hat. It felt as if a bunch of different people gave their input for each scene and the director didn't bother trying to unite it all into a coherent whole. The visual appearance of the film also suffered from poor directing choices. The action sequences were nothing more than poor special effects experiments. And during those CGI fiascoes, it was usually impossible to tell what was going on thanks to unnecessarily rapid cutting and equally unnecessarily close shots. And, for better or worse, this film is so much more "mature" (i.e., bleak and dismal) compared to the early Harry Potter films. All in all, I was appropriately planted to my seat while watching the movie, but mostly because it made me want to find out about all the good stuff that didn't make it into the movie. As for the film itself, I can only recommend it to people who are already die-hard Harry Potter fans.
