LOL. You must’ve been watching a different Dark than the one I did.
Time travel is a difficult trope to do well, because there is so much potential for paradoxes and other confusion. I always find myself going “So, if they could travel through time, couldn’t they just do X?”
In Dark, it started with a good premise, but the last season was a total wreck. It felt slapped together, like they had to come up with an ending in a hurry.
