The two main characters - I hesitate to call them protagonists - are not entirely unlikable - until the end - but neither are they in any way remarkable, except perhaps in their complete lack of foresight. By the end of the film, however, they have evolved to be fully unlikable and quite the antagonists. The film wraps with an inexplicable extended sequence that was apparently intended to be allegorical but was instead just nonsensical. I've tried my best to give you a sense of the film without resorting to spoilers, but really the film was already spoiled by the screenplay and concept.
