I'm not going to spend a whole lot of time on this one. I speculate that I may be the last person on earth to start this series so I'm pretty sure the plot doesn’t require a lot of summarizing.
I will say that I'm glad I've finished this book. I've seen the movie adaptation twice and going through the story a third time in this format wasn't really all that enjoyable for me. Overall, I think that hindered my rating, which probably isn't all that fair.
Seeing as I haven't seen the other movies nor have I read the remaining books, I'm looking forward to really getting into the Potter universe.
