I wrote a review of this for my college newspaper, and I have almost all of the same quarrels with it that you did. I felt that the second half lacked the intensity of the first half, and was sort of boring.
Great review though!
That's actually how I would describe it; the first half was really great, but the second half falls a bit short. It's great all the way through, but it loses that "oomph" that it had in the first half.
Thank you, though! That really means a lot!
