Josh Brolin’s initial reaction (spoilers)

I feel like his initial reaction to finding out he slept with his daughter was completely unrealistic and so over the top. I don’t understand what the big deal was. During the act of him plowing her when he was unaware she was his daughter he seemed to be enjoying himself. I think everyone would love to sleep with Elizabeth Olsen as she is really beautiful and sweet. I’m sure most logical guys if they were in his position would keep the secret to themselves but perhaps continue plowing her (maybe not right away but I mean if he enjoyed it the first time what harm will it cause to continue sleeping with her, right?).

Brolin returning to the prison to jail himself was such a terrible and unrealistic ending, it made me dislike the movie slightly more.
