The whole movie is a bus journey of a set of people from a rural area to a city. The film's journey begins pretty normally, then becomes witty, humourous, so much farce, sarcasm, turns to black comedy, bleakness, blast!
Yes, of course, it was set in 1941 in Yugoslavia around WWII, that's the background, but it is relevant everywhere, to everyone, at any time.
And its jaw-dropping ending reminded me of Parasite becoz that happened out of nowhere 😨😅! Believe me, You would love to ride this movie! Just go for it.
