By Erin Beck WELCH - About six or seven people sat and waited outside McDowell 3 Marquee Cinemas in Welch at about 3 p.m. Friday, about 40 minutes before "The Glass Castle" was set to start. Theater staff didn't unlock the doors until 3:10 p.m., and the first showing of the movie, based on the memoir of a former Welch resident, didn't start until 3:40 p.m. "Are we going to be disappointed?" one of the women asked.
