My take on Jack
Everyone keeps speaking about incest and how this movie deals with that theme. Here's what I got out of it.
Jack never had incest on his mind. The man was knocking on death's door, so in his last few months he's going to reminisce on the things he's done in his life, both good and bad, and he's got some decision-making to do for the benefit of Rose. When he looks upon Rose, he sees a daughter that has grown up to love him no matter what kind of father he was or tried to be. He wanted her to know that he loved her, and to know that she would always have someone to take care of her, which is why he tried desperately at the end of his terms to get Catherine (Kathleen? I get her character name and real name mixed...) and her sons to move in and be a family. But forcing a group to coexist and try to be a family doesn't always work, which is also why his commune probably failed. He wants to make things right, and while he may not be able to reestablish his commune, he very well can make sure that his daughter will continue to prosper. As the events of the movie unfold and the characters interact with each other, it's seen as love in Jack's eyes even if it isn't. In the scene at the breakfast table, his eyes water as those around him make small talk, as if this were the missing ingredient for so many years of happiness.
Throughout the movie, Jack just stares at Rose with a smile and on the verge of tears. In my opinion, he was not thinking of her in a lover's sense, but as a daughter he is about to leave. This weighs heavy on him because she doesn't know anyone else and he doesn't think that she will be able to support herself, and he knows that she needs interaction with other people to survive without him.
I am just so sick of people looking at this movie as "Hey...he committed incest and wanted to jump in the sack with his own daughter." That's not the reaction I got from this movie. I just thought I'd throw that out there, see if this is how other people saw Jack's character.
I could eat a bowl of Alphabet soup and crap a better response.
