This 2023 “Camelot” has more the nihilistic ambiance of “Game of Thrones” than an East Wing filled with art. It’s the chilliest “Camelot” you ever did see and it embodies so many of the current neuroses surrounding the revival of classic American musicals. These include: unease with sex (the barely danced “Lusty Month of May” number is about as sexy as January wind chill); fear of the narrative dominance of a handsome, confident, heterosexual male, which means that Donica gets heavy eyeliner and Burnap, for all his talent, comes off as a less-than-effectual wimp half the time; and, above all, a profound distrust of the ability of people in power, like kings and queens and presidents, to do the right thing. Such a view is perfectly valid, but begs the question: Why are you reviving “Camelot” if not just to cash in on an audience expecting something completely different? Sure, gorgeous songs like “If Ever I Would Leave You” and “I Loved You Once in Silence” are there, and technically well sung with the underpinning of Lincoln Center’s typically fine orchestra, but they are shorn of belief because the production keeps running scared of love.
