Since you were promoting a movie in Polish without subtitles, I thought I would get into the spirit of the thing.
Who said it was going to be without subtitles?
This is just a trailer. And - I suppose - even if one doesn’t speak the language - he/she may feel “the spirit of the thing” from the scenes.
The full movie will have subtitles.
Besides - nobody forces you to watch it or to enter this thread.
