This was a textbook artsy character drama. I liked it at parts and then was kind of feeling disturbed watching it at others. Honestly, I think that is what the director was going for so I guess he did a good job. Michael Fassbender really has evolved into an awesome actor over the last year or so.
I would somewhat recommend this movie to people. Again - it's super artsy and there is a lot of sex and a weird brother/sister dynamic so there is definite awkward feeling moments for the viewer.
