I wonder how much of these criticisms are being chalked up to the film or to the stupid way people view adoptees in general.
If we're not 100% happy about adoption and have angst about it we're seen as selfish (adoption means two things - happy about getting awesome great parents, understandable grief about having also lost parents. Any time I mention missing and wanting to have known my biological parents, even my friends tell me to stop being so selfish when if I was raised by an aunt or uncle they wouldn't say that). Or whenever I bring up wanting to search for my biological parents it's, "why would you be so selfish and do a thing like that that would hurt your adoptive parents?" I don't want to hurt anyone. I just want to know who I am completely and part of that is finding them. Nothing selfish about it. Anyone who has lost their parents has angst about it. It's not this apple-pie version of it people want to see/believe is there, but actually is. And from the trailers the movie seems to hit those same beats.
Just wondering how much of these criticisms have to do with the movie or people's beliefs that an adoptee showing grief, identity crises, and wanting to search as "selfish" things...
ADDING: I've seen this too with 'Place Beyond the Pines' with people throwing Jason down for wanting to his biological father as "selfish." And people have responded to other characters in the like. So with people's mind-sets being there, just wondering if that's impacting how they're viewing some things.
