Ranking the worst episode from every Star Trek series (from best to worst)

4. The Original Series - "And The Children Shall Lead" (5.2)

A ghost hijacks kids, who then hijack the Enterprise. Not every idea should be entertained in meetings and this was one of those that never should've seen the light of day.

3. Discovery - "All is Possible" (5.2)

Usually, the combination of training cadets and dealing with intergalactic government is a guarantee to be a hit for fans of Star Trek. Yet, Discovery made sure to make things as hard as possible at all times. A lot of the criticism seems directed at Mary Tillman's writing for the episode, with many fans dismissing her treatment of the cadets as condescending and belittling.

2. Voyager - "The Fight" (5.0)

Boxing and the navy go hand in hand. When you're on a ship for weeks if not months at a time, boxing became a way to resolve conflicts. It's a staple we saw done really well in Battlestar Galactica. Yet, when Voyager did it, they made it into some type of supernatural dreamscape, where Chakotay was fighting an alien in the boxing ring throughout the episode. Chakotay was a fan of the "sweet science" tracks, but the way they implemented it was hard to watch. The entire gimmick never should've made it to air and a better crop of writers should've figured out a better way to work boxing into an episode. Just lo how Voyager did combat sports in the season six episode Tsunkatse.

1. The Next Generation - "Shades of Grey" (3.3)

It's the only clip show in Star Trek history. Should tell you all you needed to know.
