Wallander's Relationship with His Daughter...
strikes me as a bit odd ... not that I think they're hinting at something creepy between the two but it just seems to me that she's way too much involved in his life. I know families are all different and some adult children have closer relationships with their folks than others but I couldn't help but think that the scene where Wallander is the one holding his daughter's hand while she's getting the ultra-sound was strange...where was her husband? Where was her mom? Heck, even the nurse thought at first that they were a couple.
I can't help but think that the whole dynamic between Wallander and the daughter would make more sense and be more plausible if instead of her being his daughter, she was his kid sister. Because I think that's what their relationship is more like than a father-daughter one....more brother and sister.
