"Mel Brook's History of the World - Part I shows its stripes right from the opening scene. In this Dawn of Man episode, apelike creatures rise up from the mud, learning to stand erect and reaching nobly toward the heavens. Then they begin bumping, grinding, rutting, gyrating and otherwise slipping back to the slime from whence they came. The movie, like these primitives, delights in being lowdown. Even by prehistoric standards, Mr. Brooks's latest comedy is especially crude... There are loads of familiarly funny gags in the film... But the movie is so sour that its humor is often undermined, because so many of the jokes are either mean-spirited or scatological, or both. Women are either explicitly predatory or stupidly decorative, and homosexuals are made fun of regularly. Bathroom jokes are everywhere. Flamboyantly bad taste, which Mr. Brooks raised to the level of supreme wit in his Springtime for Hitler number in The Producers, is this time just bad. A musical number about the Spanish Inquisition, with Mr. Brooks playing a torturer who merrily abuses Jews, is about as crashingly unfunny as a musical number can be...In Rome, we... watch a gladiator on an unemployment line, being asked... Did you kill last week? Did you try to kill last week?... As a waiter at the Last Supper, Mr. Brooks is seen asking the apostles whether they'd like separate checks. As Moses, addressed by the Lord, he mutters: Yes, I hear you, I hear you. A deaf man could hear you!"
