<p>This topic made me think about how other long-running series have ended, and I think it’s just a really hard thing to do well. Cheers and Friends did a fine job. Will and Grace and Mad About You, not so much. Breaking Bad, perfect. The Sopranos–we can argue that one forever! And though I never watched Lost, I recall how infuriating many found the last episode. At least the producers of HIMYM thought about this from the start and had a plan.</p>
