Artists are generally not subjected to the focus groups and market research imposed on films and advertising. Yet if they were, one who would score high in the demographics category is the Brazilian-born, New York-based artist Vik Muniz.
A few minutes spent inside “Vik Muniz: Reflex,” an abbreviated version of an exhibition that appeared last year at the Miami Art Museum — organized by Peter Boswell, senior curator there — makes it clear why Mr. Muniz’s work, itself as seductive as an advertising billboard, appeals to a large audience. For one thing, Mr. Muniz is committed to making art fun. “I have always taken humor very seriously,” he has said.
