Again I agree with Aberforth. I'm angry with her because I feel cheated. I felt the story was rushed and sometimes it felt like J.K had boxed herself in and had to quickly change direction to get back on track. What I'm saying is, that to me it didn't feel like she had been planning this for 17 years. I never thought I'd say this kind of thing about her, but for me, this was nothin like her usual style.
As for glorifying suicide, I personally don't think this was the case. I didn't see anywhere in the book that said, suicide is the option. Maybe, dying to save the people you love. But that is, for me, very different to suicide.
