Movie takes a creepy turn ...
...(cont.) when the sweet, old grandpa turns into a scheming, manipulative person who reads Meg Ryan's diaries and tries to mimic her personality, faking love for the husband of the woman he is impersonating, even has sex with him though he was not gay, that's ..really extreme. Plus the cold stare when Alec Baldwin confronts him/her, it was almost sociopathic and dangerous for a few minutes.
And then by the end of the movie, he turns into a sweet, harmless old man again and is willing to get into his own body. The whole thing was a bit weird for a romantic film.
