'Cause it was... so... casual.' This whole movie is so casual.
I have quite a few issues with this movie, but this is the number one thing.
Everything is just so normal and perfectly fine. They all handle these affairs a lot more calmly and rationally than they should. The scene that made this click in my head is this one: The four are sitting at their little table after they came back from the swim, as they usually do, but unlike other times, it's painfully awkward. Nobody says anything, they just fiddle with the food while glancing awkwardly at each other. Ian gets up, Roz asks him where he's going, and he just says, "Your room."
Another overly casual couple of scenes were the "revealing" scenes. The first one, Harold goes to Lil, blurts out that he saw his mother the way he did. Just like that. No mumbling, no stuttering. 'Oh, yeah, my mom *beep* your son. Oh, well.' The second, Ian is a huge cry-baby about Lil and Harold's affair. Was he really not thinking of his daughter at all? I find that so, so difficult to believe, that he threw it all away so goddamn easily.
It didn't *beep* feel real at all. The acting didn't help.
Something else that bothered me was... well... this is sick. The concept of the movie is absolutely disgusting. Look, I can put up with romanticizing couples with large age differences - whether the older one was a woman or a man. This movie, however, doesn't stop at a mere age difference. These women raised these young men. They changed their *beep* diapers. They're both their sons mothers/second mothers.
While this movie shows the shame that Roz and Lil felt... it... it still puts the relationships in a good light, I think. Despite all the disasters it caused, it's still supposed to be a real, warm, raw thing. But it's not, it's just gross.
Adore is just a 50 Shades of Grey for naive, horny grandmothers.
