“Pandamonium” (* out of four) was a rabidly bad horror movie about a girl (Oriana Charles) who starts her first day at a new office when a killer is stalking the office dressed in a panda suit (hence the clever title) and she tries to stay alive and uncover who the killer really is. Amateur hour in terms of acting and filmmaking; even the killing scenes are poorly staged and this looks like it was edited with a chainsaw. “You’re Next” and “Torment” told virtually the same story about a decade ago.
