It is strange to read the early press coverage of “Saturday Night Live.” No matter how much the show has changed over the years, the focus of the criticism is still much the same.

“Saturday Night,” as it was known when it premiered on Oct. 11, 1975, was considered to be … rather uneven. Some saw this as a flaw, others as an endearing element. Many saw the ragtag show’s potential to change TV forever.

With “Saturday Night,” which recreates the run-up to the first episode, currently in theaters and the show’s 50th season beginning — when else? — Saturday night, here is a look back at how the world greeted the arrival of “S.N.L.”

‘Simon and Garfunkel Reunion on NBC’s “Saturday Night”’

The Times did not review the first episode. But the critic John J. O’Connor did write about the second, and he included his thoughts about the premiere. He disliked the inaugural host George Carlin’s “pretentious comedy lectures” and the juxtaposition of fake and genuine commercials. “Even an offbeat showcase needs quality, an ingredient conspicuously absent from the dreadfully uneven comedy efforts of the new series,” he wrote. O’Connor admitted that he missed the first hour of the second episode because of “an unusually good dinner on Long Island” and travel challenges. So he highlighted a Simon and Garfunkel reunion on the show, which he did see. Lorne Michaels complained about this in “Live from New York,” a 2002 oral history of the show.

By the fifth episode, with Lily Tomlin hosting, O’Connor changed his tune. The format now worked, more of the humor was now “on target,” and the Not Ready for Prime Time Players were “incredibly adept” at going live. The show had become “the most creative and encouraging thing to happen in American TV comedy since ‘Your Show of Shows,’” he wrote. Could Tomlin’s hosting have anything to do with that assessment? Perhaps. In the spirit of full disclosure, O’Connor confessed to being “helplessly in love” with the comedian. (“It’s best to get that kind of thing out in the open.”)
