The Killing really should be regulated as a controlled substance. It’s impossible to stop watching it.
I finished the second season, and you may or may not be happy to know that they do finally reveal the murderer, and it looks like you can walk away from the show after two seasons. Spoilers way down at the end of the post. (Not really, though. I don’t tell you whodunnit, but I do sort of rule out one person.)
They really punch you in the face with feels in the second season finale. Get your hankies ready.
[spoiler]Okay, I’m not going to just tell you outright who the murderer is, because it would totally wreck the show. But I will say that my theory was wrong. I wish I _hadn’t_ been wrong though, because I think it would have been a much more surprising result. Honestly I’m a little disappointed in what the writers came up with. I don’t feel like there was enough foreshadowing for the audience to have figured it out. It wasn’t *entirely* out of left field, but I still felt a little cheated. I put in a lot of hard intellectual work figuring out who *my* killer was, but I don’t feel like the show put in that much work on the actual answers. Maybe I’m wrong though. Maybe I was too invested in my theory to see any other evidence. But I’m not sure I have the emotional fortitude to re-watch the show again.[/spoiler]
