For me, its Xena.
Few years back, height of covid epidemic, was living in homeless shelters. Overcrowded slums, everyone miserable, yelling, screaming, fights, abuse, rage. At one point, could feel the anger building in me. Powerless, a victim, desire for retribution. What good was trying to be better person, when all it meant was people walking over me.
Started rewatching xena, hadn't in years. Big message of the show: when surrounded by hate, violence, it's tempting to give in, to not be a victim. But you have a choice, to not continue the cycle, to make a better world. I so needed to hear that message at that time in my life.
What tv show helped you?
Currently rewatching the Good Place (mid season 2). So good.
