I was recently listening to Doug's mini-review of TOY STORY 3, and it strikes me as intriguing that he disliked it mainly for the ending with Andy giving his toys away to Bonnie, on the grounds that he felt Andy's behavior in the way he was describing all of his toys with elaborate backstories and spontaneously breaking into play with her to be awkward and age-inappropriate for Andy.
I never saw it that way. The way I always saw it was that Andy could see that Bonnie was a rather shy and withdrawn little girl, and he was simply trying to communicate with her in a way that would make her feel a little more comfortable about accepting these special toys that he was giving her. As for the playtime? Well, likewise, I saw that as Andy just trying to make her feel more comfortable and less shy about the whole thing . . . that, and yes, I'm sure he wanted to play with them one last time, but I don't see how that's awkward or age-inappropriate.
