This movie could have been so much better, but it was cursed with the original Twilight Zone (1960-64) format: Riveting beginning (5 minutes), dull exposition about relationships (18 minutes), then an interesting ending (2 minutes). This movie follows the same pattern, but the exposition section is over an hour long.
Exposition slows down a movie, but it has its place. Foreign films-especially from Europe-usually commit a good section of the film to exposition. It works in those films, maybe because when you watch a film by Wim Wenders or Ingmar Bergman, you expect it to rest almost entirely on dialogue and a strong focus on relationships. House Hunting (2013) leans heavily upon exposition, but it's in the wrong genre for that. When people watch horror movies they expect it to be plot-driven with a heavy focus on the problem. This movie establishes a great problem at the beginning, then abandons the problem for most of the rest of the movie. Instead of focusing on a solution to the problem, the actors are given s script which focuses on soap opera relationships.
Maybe if I had understood from the beginning this aspect of the film I would have enjoyed the movie more. Their relationships do help them unfold the problem, but not enough. Nevertheless I do enjoy a good foreign film, so maybe the problem is simply in my expectations.
