I am annoyed by it. I wonder if there was a longer version of the finale (promo pics showed scenes not shown) that had to be cut for time, but the second half of the episode seemed rushed, as if it had to get through so many twists and turns and so the "big moments" weren't given time to breathe and have the impact…
