Before there were any other series on this, most notably Craig Mazin's HBO/Sky Chernobyl, there was this documentary that best explained what happened that terrible night, including the some now-Ukrainians who were there working the night it happened, and ended up living to tell about it.
The series went even as far to recrate exactly what happened early that AM using one of the other control rooms at the Lenin/Chernobyl Nuclear Plant in Ukraine at the time the episode was created.
It doesn't do much post-accident exploration, as that is not the purpose of the whole Zero Hour series, but is more to focus on the minute-by-minute play of what happened in the control room.
It is fair in terms of giving a complete assessment of what happened, putting fair blame on the operators, supervisors and the Soviet system overall and not to point fingers at one specific party or come up with conspiracy theories.
