Too much time is spent creating those stunning visuals as the majestic train embarks on its voyage from Istanbul, when that could be time spent on flushing out the medley of characters that jumped on board for the ride.
That said, the experimental camerawork and the scenic itinerary at least offer some redeeming moments.

It looks so unrehearsed, so spontaneous…. just like the film where the characters probably existed long before the writer and director thought about them. We just didn’t know or care.
