An explosion of feelings and emotions in this "dramedy" subtly written and perfectly played by a great cast. Highly touching movie, as the humanity of all the characters is nicely developed as the movie goes on.
A main key of this sweet movie is as you get into it, you can not avoid merging it with your own life and family memories or happening. Whatever your own family issues may be, you are just bound to believe how deep and necessary this mess might be. Watching this movie may thus trigger regret or satisfaction depending on your own situation.
There is also an intriguing absence all along: mothers' ones. Indeed, although various families' lives are depicted, none of them includes the crucial figure of the mother, dead for some, away for others ... Besides, fathers' personalities, despite their own weaknesses, have in common their strong humanity arousing sympathy for all of them.
How to understand this very specific and compelling plot? I guess only screen writers, one of them being also the movie director, hold the keys to fully understand what can probably be linked with personal matters.
