Last year, Adam Sandler gave arguably the best performance of his career in one of the best films of 2020, Josh and Benny Safdie’s mile-a-minute instant classic, “Uncut Gems.” As Howard Ratner, the ill-fated, lethally optimistic scumbag protagonist of that masterwork of New York City grime, Sandler didn’t exactly reinvent himself; he merely amplified and twisted some of his more recognizable screen tics – his oafishness, his uproarious manic outbursts, and his pronounced sense of Judaism, just to name of his more prominent screen qualities – into an arresting, frightening new dimension.
