30 Worst Star Trek Episodes

by Kim_Kobusch_Simonsen | created - 04 Nov 2014 | updated - 04 Nov 2014 | Public

Excluding the animated series these are my least favorite Star Trek episodes.

The list contains: 9 TOS episodes 6 TNG episodes 4 DS9 episodes 6 Voyager episodes 5 Enterprise episodes

DS9 is the most stable show in my opinion. I was surprised that is was difficult to find the bad episodes. TOS differed much from episode to episode, hence the higher number of episodes on this list.

Here is how I rank the different Star-Trek-shows: TNG>TOS>DS9>Enterprise>Voyager
