Tooo much artificial and unrealistic (yes, don't believe when anyone says the opposite), mainly the climax - sadistically manufactured to look 'different'. As much "Oh-what-a-continuous-bunch-of-coincidences" as people complain about in routine commercial films that are labelled 'unrealistic'. This is more than that. That way it's not unique / different / new and definitely not a 'realistic' film as some state.
All key events from the beginning just fall in place too conveniently and unrealistically (in the name of 'magically'). Around half of the film does have a pleasant feel-good ambience, supported by a classic french'ish background score, but the rushed-up "desperate to look different / award-worthy" fabricated sadistic end just spoils everything, beware!!!
