For me the skill I value above all else in TV and film is IMMERSION. To make me forget that I'm watching a production and believe for a moment i'm there.

When it's a tragic incident this is even more important, as we are witnessing an account of real people that were injured and died.

This show does not give me that. At all. The intrusive music, swish direction, slow-motion dramatics all takes me out the immersion - and makes me feel like we're watching a disaster movie from the 1990s.

The worst thing - by a mile - is that they're all British. This was an incident in the Ukraine. Why is everyone acting like they're in Britain? I pushes the show into absurdity. I'm not saying it all has to be foreign language with subtitles, but The Americans was a great example of using real foreign language actors so that when they even spoke in English you felt it was realistic.

The actors you could lift out of any generic BBC police drama - the head of the control room feels like the police boss. The questioning in the 'interrogation' room was absurd and they were seconds away from going "You're nicked!".

They should have just made it a fictional account of a UK nuclear disaster and avoided most of the issues above.

I'll give it two points as set design wise, it looks great.
