I saw this original series a couple of years ago and was instantly addicted to binge-watching till the end. It is rather well written, superbly acted, and quite thought-provoking to say the least. If you haven't yet had the chance, I would highly recommend this series at the very least, for the pure entertainment of it.

They came out with another installment which I have yet to see. Don't know if it's as good as the original or not, but when it comes across my path, I'll certainly check it out to find out.
