Given the title, I expected Tom-ic Energy to have something to do with atomic energy (seems reasonable), with perhaps one of the characters becoming super-powered after exposure to radiation. What we actually get is just another routine chase cartoon that is executed with very little invention, the title seemingly irrelevant.
To describe the action is simple: Tom chases Jerry around a high-rise apartment and on the surrounding streets. And that's about it. The gags are mediocre and the animation perfunctory. While not as bad as the Gene Deitch era cartoons, this is a long way from the cat and mouse's glory days and is one of the weakest Chuck Jones efforts so far.
