Why does he just sit there and watch? (spoilers)
When Alistair catches Baines and Ada in the act, why does he not barge in and prevent the tryst that's about to ensue? Instead he peers through the door slates, and later climbs under the floorboards to get a load of the action. Does he just not have the cojones to stand up to them or is this some perverted voyeuristic thing? I remember reading Jane Campion (the director)'s take on him; she said that he's meant to be quite a loner (as evidenced by his leaf collection); probably completely inexperienced with women. Twice later he tries to take advantage of Ada; once he pounces on her in the forest and she escapes when she hears her daughter call--and later, after he's chopped her finger off and she's delirious from blood loss, he takes his pants off and it's clear what he intends to do. Only when she stirs awake and makes eye contact with him does he decide not to rape her. So, what do you think of why he took this vicarious thrill in watching his wife and best friend get it on?
