Would you have rather ended the season the way the Cubs did (getting swept, looking generally overmatched in the series, never leading in a single game), or the way the Blue Jays or Mets did - having leads in most games, winning a game or two, having your closer on the mound during 3 eventual losses, making big mistakes on defense, etc..
I don't like the Mets, so it didn't bother me a bit to see them blow leads, play tight, and lose the way they did. But that had to pretty painful, for fans and players alike. As a franchise with perhaps a still somewhat fragile psyche, I think the quick 'n' ugly sweep (after winning the Pirates game and Cards series) was actually an ok way to bow out. Motivating, but hopefully not damaging.
