HBO's latest miniseries, Chernobyl, has just become the highest rated TV show of all time according to review site IMDb, just one month after it premiered in the United States and the United Kingdom.
That puts it ahead of incredibly high rating TV shows, such as Game of Thrones, Breaking Bad and Planet Earth II.
The five-part mini-series delves into the story of the Chernobyl nuclear disaster of 1986, and the results of the widespread radioactive exposure.
The show received a 9.7/10 rating on IMDb, whereas Band of Brothers received 9.4/10 and Game of Thrones received 9.3/10.
Even more impressively, every single episode of Chernobyl has been rated by IMBD users at 9.5 or higher - a feat which, for four consecutive episodes, had previously only been achieved by Breaking Bad, and that was for its final four episodes.
Given the subject matter, and the fact that it's a historical drama, this level of success is relatively unheard of.
The show has also caused a massive swell of interest in the real-world events of Chernobyl with web traffic for the disaster on Wikipedia increasing 56-fold since the start of the year.
The show is available to stream on Neon, and screened on SKY's SoHo.
