I just finished watching this, about 2 days ago because I saw a review from @ernestopg last week.

Claire never saw Henry's nakedness until she was 17 and it's common for children to not really communicate what they're up to, to their parents, but she did mention it to the house help.

The movie touches on sensitive elements of relationships but it did avoid anything inappropriate contrary to how most may view this, in my opinion. Henry avoided telling Claire about their future relationship for starters, even when she suspected and wanted it to be true so badly.

While it's easy to get carried away by the romance and the flaws of it, the movie mildly managed to pass some important messages on time.

The time that really mattered was the present, which was Claire's. This is an important element because it shows how Henry's life was as much about Claire's just as hers was about him.
