I’m with you there. Personally it’s hard to get invested in the story of the CoS characters because they never accomplish anything, they always end up dying unfulfilling and meaningless deaths. Even Berg, that has survived longer than any other, still hasn’t accomplished anything meaningful to the character. The only exception to this was Morgan’s character and that’s only because Adam, in contrast to what he has done throughout the show, was benevolent and had a plan to counter her possible death.
That’s not to say that I don’t enjoy the show, I do enjoy it a lot nonetheless but feel there’s a bunch of lost potential in the story and character building side of things. Besides that, when every single encounter is designed to be a hard or deadly encounter it effectively prevents the characters to ever feel like they are getting more powerful because they are at deaths door with every fight.
Anyway, it’s a question of preference and it is neither good or bad that it is this way. Some people need that thrill to be entertained, others prefer richer stories.
