Take some time on this cold, cold day and watch Last Call, a wonderful documentary about New York City in the ’90s. It’s not the most professional film ever made, but what it lacks in continuity and slickness, is made up for in sincerity, honesty and heart-warming nostalgia. Shot by Ruth Slinger, it looks back on the ’90s with hundreds of images that the Brazilian director shot while living and working in NYC with her brother Carlos “Soul” Slinger — one of the featured talking heads — at their SoHo and Lafayette Street store, Liquid Sky. The film mostly avoids the usual “it was so much better then” cliches, and still manages to capture everything from Wigstock to Deee-Lite to Chloe Sevigny to Frankie Knuckles and Moby — plus there’s more obscure characters like the two owners of the cuckoo Lower East Side store Pluto Dog. At times it’s like watching a rough cut of the film Kids with real people, and a soundtrack of music that defined a decade.
