I really didn't care much for the book. :/ There were some parts that I really enjoyed and were pretty suspenseful, but in the end I thought it was a mediocre finish to a really epic story. I dunno, I was just left wanting more when I finished the book.
Warning - Spoilers!
Like, through most of the book Harry and the others don't even know what's going on, like - the whole tent scenario of the characters moving from place to place that lasted forever was pointless.
And the fact that EVERY SINGLE TIME they got close to achieving something and doing something right something bad happened, or someone messed up and Death Eaters were right around the corner to catch them. Like, I don't know how many times I read a scenario and then J.K. Rowling attempted to pull a twist and was like, "OH NO! HARRY USED VOLDEMORTS NAME AND THEY GOT CAUGHT BY SNATCHERS! OHHH." Like, it was entertaining some of the time but after awhile it became pretty comical.
And I was really really disapointed with Voldemort. The entire god damn book he was just running around looking for the Elder Wand and finally just realized his Horcruxes were destroyed really late in the game. In some parts of the book he was portrayed in a way that didn't really cast him as this omnipresent dark force - especially at the end during during the Battle for Hogwarts. And his character suffered from it. Voldemort's one of the best villains in mordern pop culture to surface for quite some time and at the end of the book I was disatisfied as to how Rowling used him.
The final confrontation with him and Harry was incredibly anti-climatic. She built up the final confrontation with him and Harry so much throughout all the books, and she did a really good job of keeping the Battle of Hogwarts scenario really suspenseful, but as it all came to a close with Bellatrix and Voldemort dueling everyone in Hogwarts I was just like, "What the hell." Bellatrix, who's an amazing villain in her own right, and who caused almost just as much strife in the lives of the characters as Voldemort himself recieved an end that really didn't do her justice. At all.
And the whole speech that Harry spouted to Voldemort before they cast their final spells at one another, which basically is the ENTIRE final confronation was really disapointing.
The ending was really rushed to, I dunno, it should've been fleshed out a lot better. All this stuff is happening and then we receive this really anti-climatic end and than it ends shortly afterwards.
And I really didn't like the 19 years later Epilogue. :?
