Stefan Stevenson, a sportswriter, who wrote an article last November 11 about SuperM and the K-pop industry as a whole made fans furious. 

He accused the group of lipsyncing saying, "From the opening vocal of the first song, "I Can't Stand the Rain," it was clear most, if not all, of the show would be lip synced. Most of the show was obviously tracked as the seven members spent their time frantically moving in sync with each other, which is part of the charm for K-pop fans. At other moments, live vocals appeared to seep in, or at least helped augment the prerecorded tracks. Either way, the group did a valiant job pretending to sing."

He also critized and insulted K-pop fans, especially the older ones, on a tweet he posted, "BTW, if you're over the age of 18 (and that's really pushing it) and you're a superfan of K-pop it's probably time to reevaluate your life. It's entertainment for 13-year-olds."
