There are 26 episodes of Heat Guy J,
and for the first 24, there is no reason to doubt that J is the Heat Guy.
He’s a robot. He emits heat from special pipes.
And then, in the last two episodes, the human protagonist gets addressed as “heat guy.”
This actually makes sense. The show’s opening title sequence juxtaposes their faces together.
The one on the left is the “Heat Guy.” The one on the right is “J.” Apparently that’s how it’s supposed to be.
I respect Daisuke’s decision to use nonlethal bullets in his pistol. Unfortunately, the writing sucks. The writers did not use nonlethal bullets because they had an excellent idea about less-than-lethal firearms. The writers used nonlethal bullets because the marketing department told them: “We want a teenaged boy hero. He should have a gun. But make sure there’s no permanent death and not too much blood – this a show that eight-year-olds will be watching with their parents.”
Similarly, the romance component is designed to appeal to movie stereotypes and not to realism. The hero and his romantic foil ought to be madly in love with each other, but their romantic tension is no more than lukewarm, in order to avoid embarrassment. This is a show that small children can watch with their parents. The writers don’t need to include kissing or any of the awkward realities of courtship.
There are three teenaged girls who seem to be prostitutes, but their exact job is never explained. Their inclusion might have been intended as a sop to edgy teenagers.
There is a rapidly-aging drunk woman who can’t get men to commit to her, and the characters speculate that she might be a suitable wife for the middle-aged “salaryman”/”ojisan” character.The drunk woman’s daughter is an insufferably precocious girl. This kind of character was done much better by Engaged to the Unidentified (未確認で進行形, Mikakunin de Shinkōkei).
Heat Guy J is a very PG kind of show, perhaps verging on G-rated. The final villain is PG, because he is a living, walking manifestation of a Freudian Excuse. Characters routinely make stupid decisions that ought to get them killed, but people don’t get killed, because it’s all very PG. I might have liked it better if the villainy had been more grown-up. It is still a very watchable show, despite the plot armor protecting the stupid characters. In the end, all the personal rivalries are shown to be not so bad. There are still divisions, but by the final episode, the viewer gets the impression that it would be possible for all the characters to be reconciled into one big happy family.
Contrast this kind of family-friendly reconciliation with a story like Unforgiven. A major theme of Unforgiven is that people do not forgive; when possible, people raise the ante of violence to make the game more expensive. People get wounds that do not heal on this side of the grave.
