Played By: Joel Kinnaman
The Killing is one giant misstep. The show's combination of self-importance and poor plotting left the series a favorite punching bag during its two-season AMC run. By the end of the series, those who weren't hate-watching, or hanging on just to find out the answer to the central mystery despite their better judgement, stayed around for Holder.
His complex character arc intrigued audiences, and the writers responded by giving him a larger role. Ultimately, his expanded plot was too little too late, but those who soldiered through the entire series will always feel a debt to Joel Kinnaman.
