I have just finished watching the last episode of this. The first 4-6 episodes were OK, the last 2, a waste of time. They just stretched it out too long, giving it too many twists and turns. Felt like they were constantly looking for a different angle to exploit. The final 'answer' was totally ridiculous and unbelievable.
In addition, much of the acting was wooden (or plastic - take your pick).
I wouldn't recommend watching it.
