I saw several reviews saying the lead actor did a great job as koresh. I think it was terrible casting.
Cult leaders have lots of charisma. This actor has none. I kept thinking Billy Bob thornton could have pulled it off instead of the weaker qualities of the guy they chose. No one would follow this guy. Not believable in that role.
Otherwise good story even if it is biased and ignores some of what Koresh was and the things he did. There are 2 sides to every story and this series was not at all objective.
