This was so good that I have watched it now more than once.

Excellent acting across the board, and the story is well-paced and generally focuses on the most interesting and relevant parts of this incredible story. It manages to balance the facts and scientific explanations very well against the human side of the story, so that the story feels informative, real, emotive and engaging, yet steers clear of excess melodrama (mostly).

There was one obvious miss though. I removed one star because of the unnecessarily over-long segment about shooting dogs, which was the only section of this whole drama that I felt was clearly "screen-written". It felt like cheap and totally unnecessary emotional manipulation. You can fast forward this entire section and not miss it at all, which is what I did on my second viewing.

In my view, if that entire superfluous section was simply edited out entirely this would be almost perfect television.
