So, you keep using the words, "cringe" and "cringeworthy". That's like saying it is "bad", which is fine, you get to have that opinion. But it doesn't tell anyone what it was about it you didn't like.
Battlestar Galactica, I'll agree with you on. That series is unrelentingly grim. The main characters never get any successes. They are all carrying sidearms, and every episode I am left wondering why they don't just blow their own heads off.
And the half-cylon baby whose blood cures cancer? That was just too nonsensical for me to continue past.
