I don't mind them, and for the end of a show as opposed to a story arc I think it's kind of a nice nod to the fans. With OB there were moments of celebration and togetherness in the show but it was good to see them all evaluating where their lives would go from here, and that some things would still need to be worked through.

One such episode that I thought was a really neat example of this was Restless in Buffy which S4 set up a few things to come and was also an exploration about the unseen tolls on our heroes.
