David A. Gross, who runs the movie consulting firm FranchiseRe, calls it “a completely unique two-day musical event.”

The sing-along version of the Netflix film topped the box office this weekend, grossing an estimated $18 million to $20 million.

KPop Demon Hunters Sing-Along will release on Netflix soon, letting fans perform the film’s chart-topping songs at home. The release follows its sold-out theatrical screenings and record-breaking global success.
