This "film" is really just a bunch of episodes of Johnny Sokko edited together into movie length. It was an okay show, although not my personal favorite of it's type. Johnny Sokko is largely derivative of the older Japanese manga/cartoon Tetsujin 28 (known as Gigantor in the the USA and available for streaming via Amazon Prime). If you enjoy these live-action Japanese shows from that era, then also check out Ultraman.
