I'm not sure whether I liked the book or not, have mixed feelings.
There were great parts that I truly enjoyed but there are others that did not surprise me at all.
For example, I had read Snape's story many times before, both in fanfiction sites and theories' topics. I felt like a 'deja vu' with that plot.
The parts when Harry, firstly, sees his beloved dead ones and, later on, when he awakes in King Cross were amazingly similar to Melindaleo's fanfic ("Harry Potter and the Seventh Horcrux"). Not exactly the same but nonetheless astonishing alike.
Now I understand why JKR said some people will love the book and others will loathe it. Guess I am somewhere in between.
*Always.*
