Two misfits go on a road trip and someone is murdered. This reminded me of a movie called Kiss or Kill from 1997. If you are going to kill someone, always kill a pedophile.
Although there is a fair amount of external action (never a dull moment), this is really about the psychology of the characters. The boy is the "hero" in the sense that he changes over the course of the series and becomes more man-like. The girl changes too, but she appears to devolve becoming more childlike, almost reverting to a stage of innocence as the boy grows out of his childhood fantasies. Both going in opposite emotional directions, as if something was exchanged. It comes through, but its subtle, like the girl bouncing over to her father like she is 7 instead of 17, or the boy actually smiling at one point.
I think the author (originally a graphic novel comic book) was trying to show the boy (who thinks he is a psychopath, and he is correct, he is) as he becomes a much more normal person over the course of the adventure and his connection with the girl (or her connection with him, as she is almost always the aggressor), as he develops empathy for others, even animals as he refuses to behave the same way he had in the past. He even takes one for the team at the end of the fucking world.
The ending isnt as emotionally strong as I think it should have been, but it was still a very good story. If you like this sort of thing.
It doesn't look like there will be a season 2. It was a one season arc like the comic.
I don't think I've ever been so disappointed in a show. It's the exact kind of offbeat, weird and original thing I usually love but this is so poorly written and completely unrealistic. Watching it was a chore, I made it to the penultimate episode before I genuinely forgot to watch the final one. What a lazy, obnoxious waste of my time.
