I can't help but compare Cold Case: Shinjitsu no Tobira to the american version, as a big fan of the later. Honestly, it was better than I was expecting. The cases were good and interesting, and, especially, well acted. The leading lady was phenomenal as well. However, each episode, even though it started strongly, the intensity lessen towards the end and it, somehow, felt less. The final case was really good as well, but I do wish they explored the leading lady's character a bit more, as they had added her story in that case. So, overall, seven out of ten.
