"Wild Strawberries" is a nice movie made by Ingmar Bergman back in the way back. Story: the nearness of death makes an old doctor contemplate the value of life itself, you know, the universe and everything. I remember enjoying it, I enjoyed the pleasant confusion of watching Bergman movies in my youth.
This guy is not only a doctor, but some kind of really high-achieving doctor, an award winning doctor. But of course he's not happy at first with his life, not happy about his relationship choices or his parenting experience. What does it all mean? Not so much, maybe.
Me, I think it's all much easier in the long run if one has a life of low achievement to look back on.
