‘Those who have seen this film will never forget it, whether they loved it or hated it’
Well, I certainly didn’t like it, but I also think it is ultimately forgettable. The various stories within the film (whose only common thread is that they happen during a heatwave in Vienna) are vague, directionless, and mostly uninteresting. The characters are tedious. The hitch-hiker who seems to be suffering from some form of autism is by far the most interesting character, but even her scenes become repetitive after not too long.
Avoid unless you particularly like slow-going and very formal films.
