Each Star Trek series has had their fair share of drama, controversy, and change. Some were minor (the uniforms in The Next Generation), and some were major (changing every character except Spock after The Original Series pilot). Star Trek: Voyager was not exempt from change, either thought out in advance or sudden.
When a TV show lasts as long as Voyager had, there’s some expectation that abrupt modifications will occur. Actors and actresses quite or decide to leave; networks request changes to episodes or storylines before they are aired; and producers and writers often alter scenes and dialog as the show is filming a script. All these happened on Voyager. Last-minute changes will either hurt or help an entire show or even a single episode. Thinking something like that was beneficial or harmful is a matter of opinion. However, a consensus on the opinion can’t be discounted. The items on this list - whether they saved or hurt Voyager - have either the majority of fans agreeing or comments from the cast and crew supporting a decision and why it saved or hurt Voyager.
