SEASON PREMIERE: Comic Nathan Fielder returns for Season 2 of this oddly endearing show, in which he descends upon people who run various businesses and persuades them to accept, or at least consider, his unorthodox “makeover” schemes for improvement. Among his suggestions tonight is one that I actually think has at least a few shades of brilliance: Nathan’s bright idea is to have an auto mechanic hooked up to a lie detector test while giving repair estimates. That’s a great idea. Honest!
