Du jour au lendemain

A bit of a standard feel good flick about a man that can't stand having this unexplained streak of happiness. His switch didn't really make sense to me, and the story soon nosedived into predictability.
Sort of a Liar, Liar but without the comical talents of Jim Carrey.
Gave it a star because of the theme of not being able to get out of your routine even is the routine is destroying you.
