I liked Quantum Leap, Seinfeld, and even though Power Rangers continues today the finale to the MMPR to the PR in Space era (Countdown to Destruction I/II - Astronema, Divatox, the Machine Empire, Rita/Zedd, every villain mounts an awesome attack, Andros must kill Zordon (but doesn't want to). He reluctantly does, and a wave of good envelops the galaxies turning almost every villain into dust, and turning Divatox, Astronema, Rita and Zedd human, then good human Rita and Zedd dance off -- confusing the Gold Ranger)
Here's a link to the summary of both eps
