OK. That is an anthropological behaviorism thesis; all American critics have been thrilled with the movie while Europe and other parts of the globe not so much. The exceptional ambiance of the film is constantly fighting against bad dialogue, sultry family dramas, nationalism and the heroic choir soundtrack. It really is interesting to realize that the only poor reviews talk about 'unrealistic scenario' science and physics wise, while no one mentions the obvious pseudo-heroic cocktail of epanaleptic, superfluous, easy Hollywood blockbuster doses. Watch it in 3D though as it is meant to be watched, a delight for your senses, but please don give me crap about any depth whatsoever. Yes, James Cameron loved it. I also love his films, it's true entertainment (not at all pretentious as in the case of Gravity) and I do not seek any deeper meanings. Mr Cuarón here, would have loved to take his movie a bit further, but some things are just not allowed in Hollywood.
