Blame Antonioni for creating the sub-genre: middle class people on holiday which opens fissures in their relationships. In 'L'Avventura' this made him a star and allowed many to follow and create the tedious holiday group film.
Unrelated does nothing more for the genre: it even has the same degree of uncommunication between actors which Antonioni had made a style and permits critics to talk of the "ineffable existential etc" although it can be boring when there is a lack of meta-guidance to the film, not just an inability to write or demonstrate drama and imply something by its absence.
The scenery is quite pleasant, the actors reasonably able, though there is a terrible English 'kitchen-sink' realism with most of them and this level of dreary naturalism is like a millstone which sinks the entire effort.
Watching rain drops slide down a window pane would be more engaging.
