I'm sorry, I know it's a work in progress, but I'm still struggling with the acting and the plot, or at least the bit revealed so far. I can live with the rest - Dr. Who and Blake's 7 did quite well with very little, though American audiences are a bit more demanding production-wise. However, both shows had acting that drew you into the plot, even if the plot was sometimes difficult to swallow.
The one good actor is the guy they kidnapped - which is a plot device I don't understand as it stretches credulity that you could kidnap someone and then expect them to be good at haggling for you at the next port. I suspect there's some element that better explains it that hasn't been shown yet. I hope there is.
Captain has potential and will likely slide into it once she's had some time in the role, but she's not quite there yet. The rest: well, not so much. Good fan-fic actors, but they look and feel like actors reading someone else's lines; they're wearing the role instead of living it. I'm an old-school gamer; I'd sit the cast down at a table and make them roleplay their characters through several adventures a couple nights a week for a couple or three months until they started really caring about who the character is and what happens to him/her, how they think and feel, how they react to different situations, how they react to each other. Or else put the script aside and have the actors do a lot of improv exercises together, tossing situations at them and having the actors try to think and respond as their characters would. You can return to the script once the actors have a solid feel for who the character is. Think of it as trying to find a way to take a shortcut past the first season of ST:NG and getting to the point where the actors and writers feel more like a family.
There's potential here, but it's not going to draw interest unless the actors can make the audience feel they're real. These are demos; it is understood that the actors haven't had a chance to really show their skills yet, though that "kidnapped" guy is already showing he knows his business. Still, these are the demos by which they hope to draw starting capital; the actors have to be the selling point.
As to the droid: there's no logic in a perfect simulate that blows its cover when it opens its mouth. She's acting like a stereotypical android. She needs to act like a stereotypical person - and I do mean stereotypical: she'd be programmed to behave the way some team of programmers think people behave. If someone builds a perfect replica of a person, that someone codes in their idea of how a person behaves and speaks, and they put as much attention into the coding as they put into the appearance. Consider the effort the Japanese are putting into androids that can interact with people. The only clue that she's a simulate would be that she might have difficulty understanding humor, double entendres and such, and as a bot programmed to follow instructions, she'd be lacking personal preferences or a will of her own and she'd perhaps be a little too compliant, a little too patient,- right up to the instant her programming tells her to do different, at which point all bets are off. Of all the actors, she is the only one who needs to look like she's an actor acting a role, because she is ultimately a machine trying very hard to act like a person.
