The series tells about the explosion, the heroism of the firefighters and other workers who tried to deal with the situation, and also the cover - up attempts by the Soviet authorities at that time. It's a very powerful and realistic portrayal of a huge disaster.
The HBO series Succession is not based on a true story. It's a fictional narrative crafted to explore themes of power, family dynamics, and corporate intrigue within a made-up context.
The series draws from Anne Lister's detailed diaries, which reveal her complex personal and business affairs. It showcases her determination to live life on her terms in a time when societal norms were restrictive.
