Beware: this is NOT a fairy tale with sugar coating and unrealistic happy ending. Please watch it nevertheless. Even if you prefer movies that are light, entertaining and mood-improving.
This movie shows a stark contrast between what's healthy, normal or socially acceptable and our characters, who are neither of these things. We soon learn that those "normal" people are not necessarily moral and their "socially acceptable" behaviours might be plain evil. Our characters, on the other hand, who are absolutely defenseless against society, bear all the brunt, become judged, misunderstood, discriminated against and isolated. Yet they never give up their struggle for love and self-determination. As a result, they might not be able to live happily everafter, but their love prevails nevertheless.
