The Kid premiered on January 21, 1921, at Carnegie Hall in New York City as a benefit for the Children's Fund of the National Board of Review of Motion Pictures.[13]
The Kid was acclaimed by film critics upon its release.[20] The February 5, 1921 issue of Exhibitor's Herald, contained a full-spread advertisement for the film playing at the Randolph Theatre. The advertisement from First National Pictures featured high praise from Chicago-based newspapers including this review from The Chicago Herald and Examiner:
The Kid settles once and for all the question as to who is the greatest theatrical artist in the world. Chaplin does some of the finest, most delicately shaded acting you ever saw anywhere, and for every slapstick furore in it there is a classic, exquisite scene. His action are riotous, convulsive, irresistible. The gentlest grandmother will bust a midriff. He's the best Hamlet alive today. Jackie Coogan is the best child actor you ever saw. Women wept just to see him. The Kid is two fisted. It's right glove is packed with the pearls of tears, its left with the horseshoe of laughter. The picture is perfection. Six reels that seem like one; six reels that are funnier than the work of any other human being; six reels that are sadder and simpler than anything in pictures; six reels that will atone for anything the movies have ever done.[21]
A reviewer from Theatre Magazine glowingly wrote: "[Chaplin's] new picture, The Kid, certainly outdoes in humor and the special brand of Chaplin pathos anything this popular film star has yet produced. There are almost as many tears as laughs in the new First National release--which proves the contention that Chaplin is almost as good a tragedian as he is a comedian. The Kid may be counted as a screen masterpiece." The reviewer for The New York Times gave more of a mixed reception to the film, writing: "Charlie Chaplin is himself again - at his best, in some ways better than his previous best, and also, it is to be regretted, at his worst, only not with so much of his worst as has spoiled some of his earlier pictures." The reviewer praises the plot, the comedy, the characters, and the "balance of sadness" with Chaplin being "more of a comedian than a clown", but writes that
the blemish on The Kid is the same that has marred many of Chaplin's other pictures - vulgarity, or coarseness. There is only a little of it in the present work, just two scenes that will be found particularly offensive by some. They are funny. That cannot be denied. One laughs at them, but many try not to, and are provoked with themselves and Chaplin for their laughing. This is not good. The laugh that offends good taste doesn't win. And these scenes would never be missed from The Kid. It has plenty of unadulterated fun to go far and long without them. Why can't Chaplin leave out such stuff? Why don't the exhibitors delete it?"[22]
