This series is very special to everyone obviously, I love the incredible effort to make it authentic and I don't have a problem with the language either. It actually makes sense they don't speak with a Russian accent, because now it looks as though they speak their native language, not like Russians trying hard to speak English. The only thing for me that ruins it for me a bit and I am surprised no one has commented on this, is the mixing of facts in timeline. It was just false depiction because some events (newscasts, outside world reactions,..) where displayed later and some earlier as if they occured at the same time to make it more dramatic. They even just lied at some points because of the timeline mixing. And that bothered me as someone who knows this disaster inside out. And kind of makes me sad it undermines all the effort to make it as real as possible. But still nothing can take away the Tchernobyl experience as if you were there. And I will rewatch this because of the authenticity, once all episodes have aired. I think they should make something (season 2 maybe) about the events leading up to the disaster as well.
