What do you consider Biggest Captain/Crew mistakes in Trek in an episode?
The one that just really bugs me is Voyager's episode False Profits.
Janeway beams the Ferengi up and they someone how convince her to send them back. And their argument wasn't even good.
Then, when they actually capture them, they send them to their "quarters" with two security officers (but they only name one, and make it seem he was the only one escorting them later) who are easily overpowered. The Feregni then some how get to their ship in the cargo bay before anyone notices and power their ship up so fast that Tuvok can't even stop them and thus ruin the wormhole they were going to use.
Obviously it's so early in the show, they can't get home but this just makes Janeway and Tuvok's security team look like idiots. It's season 3, what's up with the lax security when you obviously have disgruntled Ferengi who are known to do anything to get their profits.
I know TNGs got a quit a few like The Hunted and everyone's favorite Code of Honor.
What Trek moments just make you eye roll and question the writers were thinking? Any Trek era is fine, though NuTrek has so many to choose from maybe we should look at more competent shows from the past.
