I'ved never thought that the show PROMOTES the choices that Diana makes. It is what SHE needs to do, or at least what she believes she needs to do. Her future is uncertain...but the rest of the family needs to get on with their own lives...and in Dan's case take care of his own healing over Gabe. I always took the final scene to show us that Dan never did either, because he needed to take care of Diana so never dealt with his own grieving...now he can attend to that.
As far as NOT knowing what Gabe is: the creative doesn't even agree about that. But I do agree he's never a "memory". How could he be when he died as a baby but is only visualized as an 18 year old. However, you have to admit, if you are going to be dillussional about your dead son, conjuring him up to look like Tviet OR Kyle is a great way to go!!!
About the hate? People just love to complain about any award: the Tonys, the Pulitzer -- it doesn't really matter. A similar thread would have started about any show that rec'd it. I don't mean to say that these people are manufacturing their dislike of the show, only that awards dredge up those feelings.
It's art...it's subjective.
If we're not having fun, then why are we doing it?
