What a great way to end the series! I've watched since the beginning, feeling somewhat of a lull around season 6 or so, never to the level of the Dean/Cain TV series (that seemed in search of subject matter by its third season), then felt that this edition picked up towards the final seasons, transitioning into newer, younger characters and plots that moved from the effects of meteor rocks to what the future held for a maturing Clark. I loved this episode in that it brought many of the characters back from the earlier years, had flashbacks of many of the memorable scenes, integrated the best of the music of the "Superman" movies with Christopher Reeve along with the humor of it towards the end (between Lois and Clark on the stairs), and the high-impact finish that transitioned from the "no tights" era. Well done, and thank you to all that made the series possible.
