Nothing is worse than devoting years of your life to a TV show, only to have it end in an anticlimactic or infuriating way.

But some TV shows end things PERFECTLY, and they sort of make you sit down in awe.

Maybe you watched all six seasons of How to Get Away with Murder, and your jaw dropped at how seamlessly the finale called back the pilot episode.

Perhaps you didn't think you could love Fleabag more...until you watched the finale, and everything fell into place for you.

Or maybe you loved the open-endedness of the Mad Men finale, and you even did some extra research to see if your interpretation matched everyone else's.

Some shows just get it right, so use the comments below to tell us which TV shows absolutely nailed their endings. Make sure you also tell us ~why~ they were so perfect!
