(Big)Boys and their toys. An average King, focusing on the relationship between teenage boys and cars, something often fetishized. With other hobbies, it leads to lifelong obsessions and special interests of many males. Of course, since it involves boys and later men, there is also something pathological, if not somewhat sexual. Males just can't do something without mental issues or erections.
Coming of age with much horsepower. The teenage drama outsider setting, with dramatic changes of personality during the story. The seemingly first positive change, and the underlying question of why consumerism and status symbols won't go out of fashion soon make it a King work. However, it's in the line of novels he didn't really invest much finetuning in. That's mostly the case when there is just one complex character vs a problem or the world, with no metaplot and no fascinating inner struggles. In contrast, his best novels have two or multiple character perspectives and sometimes even a premise and deeper meaning that might have suddenly appeared while he let the characters tell the story or, secretly plotted, planned, and storyboarded a bit.
Just if you're into it. How enjoyable the novel can be is highly subjective. Just as Cujo might be a great read for dog enthusiasts, Christine is something for the car maniac. They feel more than the usual pride about a fancy new vehicle, and it's more about driving the route towards developing an unhealthy fixation and fetishism for a pile of metal. I'm also not sure if this special group might not find it more appealing than horrifying what happens in this story. Not just the gore, but this intimate relationship, the human-car fusion in the tradition of primitive, steampunk cyborg love.
Inspired by King being pretty high and drunk in the 80s. Cujo is one of his really bad works from that time, while others are ingenious, and Christine is somewhere in the middle. It could have been accelerated with some storytelling nitro and finetuning, but King didn't just produce en masse without care. His own fuel consumption immensely influenced the quality of his work. He freaking wrote Different Seasons, Pet Semetary, and It in this time period. What a freaking high titan of literature.
