Kyle Mooney makes his directorial debut in “Y2K,” which continues his interests in the power of nostalgia. He poked at the past during his many years on “Saturday Night Live,” and co-scripted an ode to children’s entertainment from the 1980s in 2017’s “Brigsby Bear.” And he recreated animation blocks from the ‘80s and ‘90s on his show, “Saturday Morning All Star Hits.” Some might say Mooney is obsessed with his youth. He returns to days of long ago with “Y2K,” which is set in 1999, using elements of horror and comedy to imagine a world when concern about computer safety on New Year’s Eve is actually justified, following a collection of teenagers as they try to survive the night.
