The Killing (USA) : finale

What do I hear about the finale of the USA version of The Killing ? Everyone is saying everywhere how terrible it was? Has anyone watched this? I am very interested because I love Danish original show, Forbrydelsen , so much and I am naturally curious as to what could have gone so terribly wrong! The original show's first season had one of the most powerful and thought-provoking endings ever!

Is anyone watching USA "the Killing"? See, Sarah Lund is curious too, she says: what have they done to my show?
