8PM | FOX — Gotham Darren Franich gave the season finale a B. All hail Cameron Monaghan, whose delirious guest-star performance(s) as various Joker-ian baddies was the lingering darkness on the edge of Gotham’s town. Monaghan returns madder than ever for the prequel’s final hour, which leaps forward a decade to a new dawn of caped crusades. It’s an occasionally awkward wrap-up, an epilogue-prologue origin that makes debatable decisions with the main ensemble.
