The Killing Review: Sex, Lies, and Email

I have loved all the episodes of The Killing. I do feel that having Richmond be the killer is too easy so I don't feel that he's the one, in spite of those incriminating pictures that Gwen was looking over. I'm a little confused as to what will happen next week. I read that this was initially a 13 episode series similar to Harper's Island. So I thought next week would be the final episode for the whole thing. Now I'm reading that this is the season finale, which suggests there will be a season 2. I would be torn about that because I really want to know who killed Rosie and I don't know that the question could sustain another season. On the other hand, I hate to see it all end. :)
