Last April, AMC premiered its newest show, “The Killing,” which turned out to be a critical darling. On paper, the show sounded wonderful. It seemed like the second coming of past hit “Twin Peaks.” Both shows were set in the dreary Pacific Northwest, and they both focused on the murder of a popular high school girl who actually had quite a few secrets.

Unfortunately, as time went on, “The Killing” decreased in popularity. It moved so slowly that people came to see the first season as a 12-hour-long episode of “Law & Order.” To the dismay of everyone who watched it, they didn’t even solve the murder of Rosie Larsen. It might have been the worst finale in TV history, and to make matters worse, show creator Veena Sud has said that they will still not reveal Rosie’s killer until the end of season two. OK, make that a 24-hour “Law & Order” episode.

For those of you who are somehow still interested in the second season, here’s what you missed. (And to tell you the truth, you didn’t really miss much.) The show follows three main stories—Rosie’s family dealing with the grief of her murder, the police case run by detectives Sarah Linden and Stephen Holder, and the story of city councilman Darren Richmond, who is running for mayor of Seattle and is very closely tied to Rosie’s story.

Linden was supposed to move to northern California to be with her fiance, but she became obsessed with the murder. She first accused Rosie’s boyfriend, but then turned to Bennet Ahmed, a teacher at Rosie’s school. Bennet was suspicious for a few reasons—he and Rosie had been sending letters to each other, he was married to a former student and he was Muslim. Rosie’s dad, Stan, beat Bennet to near death before finding out he was innocent.

Eventually (and I suppose this is somewhat of a spoiler), the evidence points to Richmond as his alibi falls through. The season should have ended with the police taking Richmond into custody, but instead we learned that Holder falsified some evidence, and all of a sudden, he became suspicious. The season ended on this note, and it was such a disappointing viewing experience.

But anyway, season two comes back Sunday night on AMC at 7 p.m. CDT. Spoilers from the season have been few and far between, so if you still care about “The Killing” after reading my glowing review, tune in Sunday to find out what’s next.
