I never thought of it that way, but you're right. Though, I think the female characters went off the rails a bit too. Rory didn't strike me as the type of have an affair (even if it was Dean). Lorelei back with Rory's dad, and then not pushing Luke regarding the April thing... didn't make sense.

In some respects I think the show would have been better off with Seasons 6 or 7. If only there was a way to fix the end of Season 5.
