I guess I was just bored or something because I decided to watch this movie. I kind of wish I could get that time back now. The movie had potential but just didn't do enough with it. Some of the scenes were so well done that they felt like you were there and experiencing it. I'm mostly referring to some of the silent moments between the lines. They were so well done that I kept thinking, "Wow, this is about as realistic as you can get." That being said, I found the ending very unsatisfying. I guess I sort of "got it" but it was still pretty weak, considering how much time and involvement I had invested in it at that point. I think the viewer deserved more. I've not seen Michael Shannon in much before this, at least not as a major part that I remember well, but he was absolutely amazing in this role. I'm going to have to watch it a few more times just to begin to understand some of the meanings and to better absorb his portrayal of his character. Absolutely mesmerizing. I don't watch movies this good very often. Maybe that's why they make such an impact when I do. So for me, it was a damm good movie. I just thought it could be a little more satisfying at the end. So that's the basis for the question in the title of the thread.
