Well I guess I am going to be in the minority here.
I kinda liked both storylines.
The Will story (which is the B Story) was a good way to flesh out his character without getting overly annoying. So I did not mind it.
The A Story was good. The bat couple were hilarious with the bickering, and the writers did a good job of making the viewer think that they are con artists right up to the very end. These are two characters I would not mind seeing again. And yes, I liked the "saccharine" ending. I am glad they chose not to get dark.
Add in something else good - NO SHIPPING!
So far out of the episodes this season they have been mostly strong. The only really bad one was a couple of weeks ago where the shipping was unbearable.
