I just saw "Oldboy" (the Korean one) a few days ago and I really enjoyed it, but I just don't get why Mido (Oh-Dae Su's daughter) can't remember her father's face or name.
I know she has been hypnotized and everything but she still had a childhood and her life, and at the beginning of the movie Oh Dae Su wants to talk to her on the phone for her birthday, that means she can speak/understand people, so she was obviously old enough to remember her father's face and/or name... A few weeks later her mother is murdered (and Oh Dae Su is false-accused because the police can't find him). It's such a tragic and important event in a life I can't believe she forgot completely about it and the name and/or face of the one who killed her mother only because she has been hypnotized.
Plus, if Oh Dae Su doesn't know her name (Mido) that means they changed it as well --and that she completely forgot about her old name. Is it possible? So maybe Oh Dae Su can't recognize his daughter because it has been too long and because of the hypnosis, but is it logical that MIDO doesn't recognize her own father?
