Auggie, I finally saw this flick. I really enjoyed it. I was deeply moved by it, and Bonnie was as always fantastic.
Regarding the time leap in the end:
There were some deleted scenes on the dvd. A whole subplot with Bonnie's boyfriend which was completely cut from the film. A lot of the dialogue between the two women at the end was originally between Bonnie and her man. I know that seems odd, but it worked somehow, and it was in the present.
I guess the director thought that having the two mothers meet at the end was more poignant.
Anyway, a very lovely movie.
