2-3. I would agree that it's somewhat overly long. But if one can endure the lack of conflict, they're likely to find a gentle sort of beauty in the way the lead character evolves from a shy young man into a good-humored, patriarchal figure, gradually finding his place in the system of life as a father figure to generations of young boys. It really does require some patience to get to that point, however.
A lovely charming film. Donat is at his best here, arguably his best performance after 39 steps. Greer Garson is a personal fav of mine, she was just a treasure. One of her earliest films, yet she shows her chops and elegance off nicely. Very similar to her performance in Random Harvest actually. Sam Wood is interesting as I know him more for his Marx bros films. Cool to see he also made films like this. Great story
