I'm not a huge fan of musicals by any means but a song and dance number done right and stylishly can be very entertaining. There was an episode where Wilfords girl sang a song before she came to his side of the train where it was pretty cool and done well. This episode however, while eating dinner a man went to the piano and played and sang beautifully. But this served no purpose for the story. Also, it was very convenient that he seemed to be so talented. This is supposed to be a post apocalyptic story where a smaller group of people managed to survive. The more people that happen to have those kind of skills and more so showcase them does not add to the story. It does not enrich the entertainment experience. All it does is highlight poor and lazy writing & effectively work as filler. Good writing does NOT routinely add things for filler. Also every episode starts with someone talking and just before the opening credits they mention snowpiercer's name and how many cars are on it. I'm not sure of the purpose for that but at this point it does a only annoying and another of the examples that showcase the sup standard capabilities of the writers responsible.
