Star Trek: The Next Generation's finale, "All Good Things," has been lauded as one of the best Star Trek finales across the board. It brought all of the crew together and ended with Captain Jean-Luc Picared [Patrick Stewart] joining in on the poker game for the first time. Executive producer/showrunner for the series' seventh season, Jeri Taylor was quoted in Captains' Logs The Unauthorized Complete Star Trek Voyages by Edward Gross and Mark A. Altman, as saying that they "knew since the beginning of the season that that episode was coming at us and would have to be done, and it was intimidating."
Taylor went on to say that "any final episode of a series is unique and important and for a series like Star Trek, which has cut such a niche in the Amercian consciousness, the expectations are really very high." And the fans were expecting a lot out of the last episode of a series they'd followed for seven seasons. Brannon Braga came up with the idea of time sliipping, and originally he'd had the idea about jumping through time with Alexander, Worf's son.
He wanted Alexander to experience a time slip that would have him trading places with his future self twenty-five years into the future, but the future self would return to the past. It was a Worf/Alexander storyline that could have paved great inroads in the father/son relationship that didn't really end on a good note. It wasn't until Star Trek: Deep Space Nine that Worf [Michael Dorn] got to repair his relationship with his then adult son, and even then, that wasn't done in the best of ways.
Quite frankly, this is a story I'd still like to see as we never saw Alexander's growing up years. It was a great jumping off point for the final episode of The Next Generation, but there was so much more story to mine between Worf and his son. And it's unfortunate that we never got to see much interaction between Worf and his adult son. If Worf could be brought back for at least one more adventure, I think Alexander should be included this time around.
