The constant zooming in on Nadia's breasts is grim, their audience are mainly women and I'm sorry but I'm not interested in seeing close ups of her ageing breasts and neck. She's insecure about her neck so I get the impression that Mark films her breasts and neck so that when/if she watches back it hightlights the area shes insecure about. He is cruel. Perhaps this is Nadia's way of thinking Mark still finds her sexy but from an outsiders point of view it tells me he is sex starved and would shag anything that moves given the opportunity.
