I wish I had as much fun watching this as everyone else seems to have had. Porumboiu's love of cinema seeps through all his references to other filmmakers and other films, whether they're overt or not, and while cinema clearly plays an important role in the characters' lives and shapes the world they live in, its meaning lacks any real depth. Shells of characters make decisions that are never particularly believable, and don't let me get started on the central relationship. Ideas, relations, truth are left too ambiguous and there's a burden on the viewer to create meaning to fill in the movie's gaps.
The whistling language, however, is fantastic, though underused. I wanted to see so much more of it—a more in-depth look at its structure, its learning, how it functions—because what we do see is so fascinating.
