Stunts

Most of the basic aspects of this movie are pedestrian: camerawork, acting, writing, etc. The plot is super thin, leaving lots of time to show, at length, how movie stunts are done. That in itself makes it sort of an interesting watch, as stunt work is usually covered only in home video special features. Plus, the 1970s, I have gathered from watching movies (eg not from books or research), were sort of a Wild West of stunts, with crews taking outrageous risks to capture something new a hair's breadth from disaster. Check out this train stunt, for instance (go to about 2:45): 

Anyway, Stunts overdoses on 1970s stuff - eye-openingly hideous interiors (many shot at the famous Madonna Inn), casual sex, grim partying, terrible men and the stuck-up/badass women who for some reason fall for them, Robert Forster calling something "heavy." There's a scene when a hairy little guy is makin' it with another guy's wife on a waterbed inside a van. The husband shows up with a shotgun, and the hairy little guy makes a cruddy joke about President Carter. If you'd thrown in an eight-track and a shag haircut, you'd have the most 70s scene of all time. 

Unsurprisingly, the stunts are pretty amazing. The script sucks. The casting has some pleasant surprises, and Richard Lynch is not one of them. Notably, this was the first film released by New Line, which had previously only done distribution. It's a long, long way from Stunts to The Fellowship of the Ring.
