The ending of POWER RANGERS LOST GALAXY (1999) goes way harder than it needed to. The colony finally reaches its destination, the Rangers go their separate ways, and the series ends with a genuine sense that an adventure has come to an end.
The final episode of SISTER, SISTER (1994–1999) bringing things back to the moment Tia and Tamera first met is such a simple choice, yet it hits so hard. Six seasons later, the show ends by reminding you of the exact moment everything began.
