Peter Debruge Chief Film CriticWatching Iranian director Majid Majidi’s “Sun Children,” I was reminded of “The Florida Project.” One of the best films about children of the 21st century, “The Florida Project” takes place within a stone’s throw of Walt Disney World, where it seems a dream too much for its neglected kid characters to visit, until, in the film’s last scene, they enter the park. “Sun Children” presents this scenario in reverse.
