Okay, I have finally finished reading Harry Potter and the Deathly Hallows, so now I can finally weigh in on some subjects I've wanted to discuss, but didn't feel like I should without reading the book itself first.
First off, though, here's my final ranking of all the books in the series, after having reread the first six before getting to DH:
1. Goblet of Fire
2. Half-Blood Prince
3. Chamber of Secrets
4. Deathly Hallows
5. Sorceror's Stone
6. Order of the Phoenix
7. Prisoner of Azkaban
Deathly Hallows might have been a little higher had the first half not been so meandering. Once they actually found out what the Deathly Hallows were, the book was fantastic, but getting there was a little sluggish at times.
Now, onto the aforementioned subjects I wanted to weigh in on.
Heh, this got a lot longer than I thought it would. *laughs* I think that's about everything I wanted to say, but if I think of anything else, I'll edit it in later.
