It's a beautiful, sad and full of metaphors story about being forced to realise whether you've been living your life to the fullest.
It IS hectic and is basically a comedy of errors, yet with very good writing and clever dialogues.
I think those leaving negative reviews took the story too literally, whereas it's a beautiful and crazy combination of all the things in life happening at once - it kinda has the vibe of 1967 film Oscar, just more serious. A really touching story with real characters and great acting.
