With a banter that centered around the loneliness of the Number '7' and asking the question "What is the meaning of life?" to the point of showing Nihilism in a good light, this show caught me right off the bat.
As the show progressed, however, I found that the plot became increasingly difficult to follow, with key elements being embedded in the understanding the various permutation and combination of numbers. The story soon transformed from a murder mystery to a math/computer geek's wet dream come true. Even with all of that, given that the pursuit of the truth was done with an emphasis on 'logic' the final revelation was so far out there that you'd need the Hubble telescope to find it.
While the show is enjoyable in its build-up, the events immediately prior to the final revelation along with the revelation itself fail to keep the plot tight and focused. In the end, too much time is spent on abstract philosophy and less on the actual crimes committed. If the first few episodes were not thoroughly enjoyable for their MIND F**K moments, I wouldn't have enjoyed this show at all.
