I agree. ASP brought Jess and the bridesmaids. So it would be naive to believe that she would write an easy ride for RL this season or the next (if there is/was a next season for RL). But big twists usually didn't come from nowhere with Amy.

And, as others said, she didn't undervalue main characters like DSR. That's something that Rory and Logan fans have been complaining since the first half of the season.
