Seasons 1-4 were phenomenal. Seasons 5-6 weren't as good, but still really solid seasons with some fantastic episodes. Season 7 started out great with its first two episodes & a few other gems, but for the most part was downright horrendous. The 100's final season ruined the entire show arguably more than Game of Thrones' 8th season did for itself. It's as though everything that made The 100 what it was for the first 6 seasons got thrown out of the window in favor of spiteful, terrible writing. What was once my favorite show has no rewatchability after Season 7.
