Having not read any 1 of the HP novels, this opinion is based solely on having seen the movies.
This said, I did not like the ending of DH Pt.2.
I did not like it one bit.
“19 years later”— When this appeared on the screen I thought I was watching Star Wars: Episode 1,2, and 3 all over again(and with the same diminishing level of interest).
Though HP was an action pack series, with many layered characters, I feel Harry Potter suffers from Asperger’s. Harry never, ever displays any ounce of empathy to the plight or death affecting his friends, he merely frowns, as if expected(or trained) to.
