There are various places, of course, were we could choose to "end" their story, and reject the rest of the crap from the writers: I suppose you could argue that year seven wan't really "Canon" since the Palladinos left; but I liked what we got from 7.01, 7.03, 7.05, 7.08, 7.13 and 7.18 so much that I guess you could choose the final image in the Maze as the end, or after the phone call in 7.20? I guess you could even go so far as the image of Rory trying on Logan's ring, and smiling. (What was that about?)
