Answer: Gleaned from the Internet: Some critics criticized the premise of so many one-off battles that were introduced and concluded within one or two episodes. Others felt the first-season plot lines were overly simplistic and never progressed or developed through the season. Also, the rivalry between Iron Man and the Mandarin also failed to capture viewer's attention.
