The plot has greedy schemer Harvey Korman trying to become wealthy by grabbing land associated with a new railroad. He must drive off the present owners, who live in the western outpost Rockridge. Part of his schemes involves giving them a black sheriff (Cleavon Little), who soon gets a sidekick (Gene Wilder).

It is hard for a slapstick comedy to be a good film. The plot isn't much, and the setting exists mostly to set up gags and jokes. The film's quality becomes dependent on how good these gags and jokes are. How funny they are may be subjective: cowboys farting after eating a plate full of beans may be hilarious for a sixth grader, but not so funny for others. On the other hand, youngsters may miss the humor in Yiddish-speaking Indians.

Some moments in "Blazing Saddles" are funny. The theme song (by Mel Brooks) is a riot. Madeline Kahn's Marlene Dietrich impersonation scores some points. Dom DeLuise has a great cameo as the director of a gay chorus line. Howard Johnson owns an ice cream parlor with a sign saying 'one flavor'. But most of the humor is more silly than effective, not enough to overcome the thin plot and characters.

Kahn got an Oscar nomination for Best Supporting Actress for her performance. Comparing her Dietrich-like character with the real thing, Dietrich was a lot more fun in another western comedy, "Destry Rides Again" from 1939. Another difference between the two films, besides the quality of script, cast, plot and characters, is that "Destry Rides Again" seemed to have a focus, a direction, while "Blazing Saddles" wanders amiably but aimlessly.
