It's the best reviewed show on IMDb currently and the show everyone is talking about since Game of Thrones came to its rather tepid end.
Like Game of Thrones, Chernobyl is a HBO show and is also shown on Sky Atlantic.
The five episode miniseries is a dramatisation of the Chernobyl disaster, which is still the worst nuclear disaster to date.
On April 26, 1986, the no.4 nuclear reactor at the Chernobyl power plant lost power before completely exploding and exposing the core.
The Chernobyl accident is considered the most disastrous nuclear power plant accident in history, both in terms of cost and casualties. It is one of only two nuclear energy accidents classified as a level 7 event - the maximum classification - on the International Nuclear Event Scale, the other being the 2011 Fukushima disaster in Japan.
The show explores the immense personal and political fallout that followed the disaster for years after the event.

The fifth and final episode will air at 2am on Tuesday 4 June on Sky Altantic. it will then be repeated at the more civilised time of 9pm that night.
The finale is titled Vichnaya Pamyat.
