Heroes (2006-2010)? That was one of the most boring and monotonous serial shows I've ever attempted to get all the way through. I watched every single episode of that suck fest hoping something would happen, nothing ever did. Just the same old thing over and over. I was like an obsessed gambler thinking the next one was going to be the big score. To this day Heroes holds a special place in my heart as the most disappointing waste of time serial show I've ever watched all the way through.

BTW, I liked SG1 and Atlantis, both were good shows and I watched most if not all the episodes. Never watched 200 so no comment on that one. Some remarkable ones I've seen lately; The Mandalorian, Star Trek Strange New Worlds, Black Mirror, Silo. Some awful ones; From (for lack of a cohesive plot) and Last of Us (for being gratuitously violent).
