(CNN) If the reaction to Monday night's "Chernobyl" finale is any indication, Jared Harris could be in the mix for this year's Emmy Awards for the first time since his acclaimed run on "Mad Men."

The HBO limited series, called by some one of the most harrowing series of the year, aired its last of five episodes, bringing to a conclusion a tale that highlighted the missteps and mismanagement that led to the tragic 1986 nuclear disaster.

In the finale, Harris's Valery Legasov and others testify at the trial of three men who are accused of causing the accident.

Legasov uses his time to explain the men's shortcomings and, more boldly, the flaws in the country's whole nuclear system -- a huge embarrassment for officials.

"Every lie we tell incurs a debt to the truth. Soon or later, that debt is paid," he says in powerful courtroom testimony that will very likely live long in GIF form on the internet.
