Review: It’s ‘Saturday Night,’ not as edgy as it really was, celebrated in a nostalgic haze

On October 11, 1975, everything transformed at Studio 8H within New York’s Rockefeller Center for comedy, television, and a group of unrecognized jesters. Half a century later, “Saturday Night Live” stands as a cultural foundation (though not quite the countercultural force it once was). However, in Jason Reitman’s overly packed, high-energy “Saturday Night,” a dramatization of the lead-up to that historic first broadcast, you sense more the voice of contemporary preservation than the electric atmosphere of revolution.
