I'll always remember one of the few times we saw him out from behind the helm and they showed him as an experienced mountain climber. This, from a fellow who was born and raised his whole life aboard cargo vessels. How and when did he learn to climb outdoors??
He didn't spend literally his
whole life, every single day, aboard ship. The
Horizon visited various planets, including Earth, Draylax, Vega Colony, Trillius Prime, and the Teneebian moons. Apparently the Draylax-to-Vega run was a regular route for them. So they would've had opportunities to visit planet surfaces on occasion.
I just never got the point of the killer Bs (with VOY, too) of creating these interesting characters in the series and then never using them. It's their premise, their series. They're the showrunners. If they wanted more Travis or Sato or Kes or Kim, they had the power to use the characters more prominently--characters they created themselves.
It's not quite that simple. VGR and ENT were both on UPN, and that meant they were subject to more executive meddling than the syndicated TNG and DS9 were. For instance, Berman & Braga didn't want ENT to involve time travel, but the network was uneasy with doing a prequel insisted on having something that connected to Trek's future. And B&B didn't want the ship to have a transporter, but the network insisted that it needed one so that it would be more like the familiar Trek we all knew.
I think the first season of ENT actually does a pretty good job of being a smaller, character-driven show first and foremost, with the sci-fi or action content being fairly basic and serving mainly to put characters into interaction or conflict. But it seems that in season 2, they were pressured to emphasize action and high-concept stuff more (for instance, if "The Catwalk" had been a season 1 episode, it would've focused more on the crew tensions in that claustrophobic space, while instead it ended up being more about fighting space pirates). And then seasons 3 and 4 were huge action-packed stuff all the way. Maybe the network also pressured them to emphasize the more popular characters at the expense of the others?
Well, that's just speculation. But it's definitely wrong to assume that showrunners have absolute power. They have bosses they answer to as well.
I think ENT (as it ended up) perhaps should have taken the stand from the beginning to go the route of TOS. Have the three main characters as the stars up-front and the rest of the cast as supporting and at the end of the eps credits, as TOS did.
Like I said, I think the first season did a relatively good job at being an ensemble-driven show. It was just later on that it started to feel more dominated by a few central characters.
