A fitting end to the series as a whole. It maybe dragged in some parts, and had a lot of exposition but I can't really see any other decent way it could've gone/wrapped everything up. I think my favorite chapter was probably the one about Snape and Lily's childhood; I always found that era of the Hogwarts timeline the most interesting, so that was fun. I do wish we could see more Lily/James interaction though. Because we know they fall in love and have a kid but we rarely get to see them in flashback where Lily doesn't hate his guts. 
 I also am really glad I read this because there was a lot of rushed stuff from the movie adaptation I just didn't GET but the book slows down and explains almost everything I was confused about. 
 I've seen at lot of complaints about the epilogue among reviewers. Personally I liked it so I don't get where the hate is coming from. 
 So yeah, good end to a good series.
