The writers of this show had one last trope to pull off which they hadn't used already: a lengthy flashback to build story and momentum. Good enough, as episode number six of Gotham's first season boastfully sinks its teeth into comic-book substance, stylizes it, and finishes off with a staple coat of paint. The result is an episode so silly that it's actually good.
A killer known as The Spirit of The Goat had terrorized Gotham city ten years ago. Harvey and his partner Dix had put him down for good, or so they thought. With the same M.O. resurfacing in present day, Harvey must confront the ghost of his past and nail whoever is behind all this. The standard characters make their presence, with one exception: Edward Nygma gets extra screen-time here. His appearances may ring false half the time (The wolf-cabbage-goat riddle is done to death), but the fantastically placed Easter eggs for a DC Comics fan are all there.
More trouble for Gordon, as the MCU inches closer to put Gordon in jail for the supposed murder of Cobblepot. Conspiracy, visiting old partners, new character arcs ensue: the glorious goofiness of it all being the crown jewel of the narration. Part of the reason why it works instead of being ham-fisted to boredom is because it is entertaining. No complaints there.
Gotham has still a lot of catching up to do, and God knows it will probably never equal the brilliant inventiveness of The Flash. But this is a welcome, if foul, change to the series which, let's face it, actually benefits from its unintentional hilarity. I'm already looking forward to more.
