The last episode of Gotham was pretty bad. The pacing was terrible and Batman's execution was poor.
What they should have done was use more camera tricks. Only see horror movie-inspired glimpses of him as he moves. See the aftermath of his actions. Shit should be escalating, after ten years of peace the superpowers of Gotham's underbelly start to move again and things look like they can get worse than ever. They should have the police respond to emergencies only to see gangs already pummeled and tied up. Everyone acting apprehensive as this wild card shows up out of nowhere and turns the tides. Someone, maybe Penguin, realizing that a huge shadow is engulfing Gotham's underworld, and none of them were prepared for it.
Rather than show what Batman looks like clearly, they should have shown him from the back. As Gordon turns on the searchlight, Batman stands on a building and perspective puts him right in the center of it, looking up at it.
