I agree with another user who says they explained the science behind this tragedy very well, and in a very entertaining fashion I might add. The final episode in the court room is one of the most interesting, informative, and well written pieces of film I've seen.

I arrive at an 8/10 because I have to take two points off for pacing. This is only my opinion. One of the storylines in particular (about dogs) dragged on far too long in my opinion. It seemed like nearly an entire episode was dedicated to a fairly basic concept with somewhat shallow characters that added very little for me beyond the initial shock value of it all.

My opinion on that aside, this is gripping, dark television at it's finest.
