In 2015, M. Night Shyamalan released his best film in years, found-footage nightmare The Visit. He returns to a conventional style with Split, which may or may not delve into the supernatural, but definitely flirts with some very weird science. It also has a killer cast; James McAvoy alone gets to play 24 different characters.
