This wasn't one of the better stories, one reason being it's a tired story, one I've seen on many TV shows and movies: a developer wants to build some place and have the people of the neighborhood live elsewhere. They always make the people all nice mothers and old ladies and homeless and harmless guys and the developer into a ruthless villain. It's really become a cliché.
That's the story with the one, which has special significance for Batman because "Crime Alley" is where he saw his parents murdered. (You'd think he'd like to get the area cleaned up and changed!)
Roland Dagget (Edward Asner) is the villain developer and he has help from "Mr. Nitro" who is good at blowing things up. The suspense comes in when an explosion is supposed to wipe out some of the neighborhood and whether Batman can prevent (as if he doubted the final result). Speaking of explosives, I'm not surprised an episode which includes Asner is sub-par since everything he's done post-"Lou Grant" TV days has been a bomb.
There was one good scene with the Batmobile and trolley car headed toward a big collision on steep streets which sure looked like San Francisco.
