With GoT now concluded and a lot of people complaining about the ending, I am wondering what you all think some of the best and worst TV show finales in history have been.

I remember being really frustrated with the finale for the X-Files, but I have to extend that to the entire last season.

My favorite TV finale was Lost (I know I go completely counter to the trend here, but I’ve re-watched the show from start to finish multiple times, and there are not as many unanswered questions as a lot of people seem to think).

What are the best/worst finales from your point of view?
