This is the thing that bothers me so much about this show. Everyone everywhere jumps straight to attack, violence shoot first!!! Instead of just talking.
This was the same problem last season- yes it was a ship full of prisoner so be wary, but both sides were dumb because they were the only people left on earth and more diversity in skills and genetics is how you get a successful new world. What the hell was dioza going to do with a bunch of violent criminals anyway? (not that they necessarily were all violent, but it seemed that way)
So this season we start off in a brand new place, fresh start, yay! And the people from this new planet start off attacking, and then wonder why 3 of the 4 of them are now dead. Talk to the ship, find out what's going on, who they are, why they are here.... how did they get there after 200 years etc. Why jump to "take the bridge, lock people up" We somehow know how this ship works 200 years later when none of our original crew still exist. I mean, their other ship could still exist and be functional to a degree, but then why are they still on the planet if they have a ship?
It just seems to stupid to me that everyone starts off killing people instead of just talking to them/trying to work together.
