I just read it yesterday. I enjoyed it. I also thought Snape's death was the most tragic. Snape asking Harry to look at him one more time as he dies so he can see those green eyes again... . I was pretty much positive that Snape was a good guy from book one on. I also knew Harry was the last horcrux. I thought that was very obvious. I loved Fred saying on "Potterverse" that Voldemort could move as quickly as Snape confronted with shampoo when he needed to! LMAO! One of the very few LOL moments for me in the book.
Overall I think that Harry Potter is a very enjoyable series, though it certainly isn't my favorite series. I think there is much better written stuff out there, even for children. In fact I have never reread any Harry Potter book, though I may one day now that it is all over. Snape is certainly the stand out character in the series in my opinion even though I am not a fangirl or his (that honor belongs to Lupin ). I never felt much for any other of the characters, not even Dumbledore or Harry. Though I did enjoy reading about them. I thought that Voldemort was a very predictable villian and there were never any surprises about him from like the second book on.
I think where Rowling's talent lies is not so much in character or plot really, but in world building. The wizard's world is awesomely realized and I always loved all the little wonderful surprises she put in it and showed us and Harry. I think I loved the Weasly's look into the magical world the best. Just an everyday average wizard family and yet what a family it was! I always loved all the times Harry spent there.
So now that the series is over my opinion is that it was an enjoyable ride, very funny at times and almost always magical and wonderous. As for plot and characters, I found them not as developed as the ones from my favorite stories. I also think that Harry Potter is way over hyped. In my opinion it's not worth the hype, but I don't think they are bad stories either. I wouldn't have stuck through them to the end if I had though that. Over all I would say Snape and a look into a wonderous and magical world is what made these books.
