TV Seasons Whose Best Episode Is Their Last One

Television season finales can be difficult to execute properly. On the one hand, a good finale should really feel like the culmination of the storyline running all season, tying together all the plot threads and characters arcs for a rewarding payoff. On the other hand, unless the finale is also the end of the whole series, a season's end should also leave enough questions unanswered for audiences to come back the following season.
