I've just finished HP7 and agree with the OP - it's the book I enjoyed most in the series. I started reading the HP books to entertain my young son 5+ years ago, but it was like a chore. Too many langours in the plot and the writing seemed pedestrian. But as the target audience of the books increased by one every year, reading the books became more fun for me. Eventually, I started competing with my son for who reads each book first and this year, I won - he found the absence of school in HP7 a major turn-off; for me, it was a major plus.
The book did still drag a bit in parts, but the action was generally fast-paced and it was good to see characters and plot devices come together & be resolved. I think it brings to a close the 7 year story arc in a very satisfying way - given the nature of the story, it could only really end as it did.
