Season 1s are great, setup, some payoff, a bit of lead into the overarching story. Then season 2 to X. The heroes win and then lose in the final episode, cliffhanger to next season. People get bored. Final season is announced and they wrap up the show.
And then just think about how many fantastic shows get cancelled in their first or second seasons. I’m still bitter and upset by Almost Human.
I’m here to second the bitterness about Almost Human (the casting was perfect for the two main characters).
I’m also sad about Journeyman.
