Everyone has been saying how marvellous and satirical it is, although I have to admit to not really liking it.
Our main protagonist is a gambling addict loser who shouts everything on a setting of 10. It is as if the director has said 'I want you to be angrier in this scene than the last one.'
Then there is the excessive body count, often involving people who have already been given a few lines. It is not like Star Trek, where they take the expendable and speech-less crew member to the new planet surface, only to see him gobbled up by the human-eating plant or crushed by the unexpected avalanche. This is like a loop of the summary execution of Nguyễn Văn Lém during the Vietnam War.
I realise that the screenplay has been translated from Korean and re-dubbed in English, and that some of it must have been a Netflix rush job to assist boost their share price. Now that's a thought, given that the theme of the show seems to be 'runaway capitalism is bad.'
The production company took over a South Korean town to make the movie all without CGI, although with lavish sets and hundreds of extras. Then, as a small counterpoint, they have a refugee from North Korea in the band of players, although she must be wondering whether this is even more totalitarian than up north.
And, as Simon Cowell would probably say, 'There can only be one winner'. {Korean trailer with English subtitles}
