Is it pretty good? It's one of the few old-school King books I've never read. I enjoy the movie, it's a marriage of my favorite director and author, but it's not one of Carpenter's best and the story (at least what I know from the film) isn't one of my favorite King tales either. It's a fun idea that made a fun movie but I've never been excited enough to sit down to 500+ pages of it. Christine is not It or The Stand in length but it's also not one of the shorter novels like Carrie or Cujo as I expected it would be. I'll probably read it before too long but I've seen the movie a lot so it's not high on my list of things I'm dying to read.
I think it is a great book, despite the mid-book POV change. It takes a minute to adjust (and shift gears, ha) but I wouldn't call it a flaw. Where is it written that a writer (who is the Creator of his own world) can't tell his story the way he pleases? King has always experimented with different ways to tell a story (
IT, Dolores Claiborne, DT series) and I'll eat my shorts if, subsequently, half the writing population hasn't tried to emulate him.
Christine is about high school, first cars, fighting with friends over a girl, learning responsibility, and, of course, death. King wrote a slew of books early in his career that scream Bachman Turner Overdrive, machismo, and demolition derby horror.
Christine fits in this category.
