Fans and critics have complained about the season one finale of the show, which promised to resolve the season-long investigation into the murder of Rosie Larsen, but instead ended with a cliffhanger leading into the recently announced second season.
AMC president Charlie Collier said that studio executives hadn't anticipated such a backlash.
"We underestimated the passion our viewers have for closure within this season," Collier told EW. "It was never our intention to misguide the viewer.
"The audience has an important voice, we heard them and don't take them for granted. I stand by [The Killing showrunner] Veena Sud, and risk-taking is what we do; cliffhangers are a staple of TV and a huge part of mysteries."
Collier added that he wouldn't change the ending itself but did wish he had tried to manage viewer expectations more carefully ahead of the final so as to help mitigate the disappointment.
The series, which stars Mireille Enos, Billy Campbell and Joel Kinnaman will return on AMC for a second season in 2012.
