Loved the show from season 1 through 5, where they sort of “soft ended” the series as the show was handed over to a new team, that team kept it running decently for a couple of seasons before it started to run downhill.
The aesthetics changed, the tone changed, the writing kept getting worse and the show prolonged itself (and is continuing to prolong itself) into mediocrity. It’s one of those cases where they had a complete and affecting story, but because of increasing revenue the network (CW) decides to bleed it dry.
I haven’t watched an episode since early season 10, where a group of high school girls had a surprisingly touching musical re-enactment of past events in a sort of 200th episode milestone tribute, but I don’t have any faith that it’s gotten itself back on its feet.
I will recommend the first 5 seasons though, just stop at ‘Swan Song’ and you’re good!
