I think the Lynch plot line might be the final nail in the coffin for me. I get it, they wanted to end the show with a big spectacle, because it was the finale and it had to be memorable, with a final big cross seasons unsub and explosions (literally).
But criminal minds was not that. Not at the beginning. I would say that the first big, continue across different seasons unsub was Foyet, who was introduced at the middle/end of season 4 and was gone by episode 9 of season 5. And then the next one was Mark Hamill? In season 8? And he lasted one season. And there were a bunch of two parter unsubs here and there.
We could’ve had a last season that went back to the beginning, with maybe a more complex two parter unsub, and the big dinner party at Rossi’s with heroes playing while they all dance.
Instead, we got the plane exploding.
