Perhaps I’m just desensitised to sex, and stories about sex, but for the most part the regular sight of a naked Michael Fassbender shagging, showering and/or wanking did nothing for me. His “Brandon” is a New York office worker who is obsessed about sex and who works in a team of permanently horny men led by his married but odiouly indiscreet boss “Fisher” (James Badge Dale) who also has a lot in common with a rabbit. “Brandon” has no problem attracting women, or paying for their services, until his sister “Sissy” (Carey Mulligan) arrives for a visit. He’d ignored her calls for days hoping she’d just go away, but he’d also forgotten that she had keys to his apartment - and once ensconced, she was in no rush to go anywhere. Obviously, this curtails his life of inflagrante delicto, and so things become a little more awkward, risky even, as he has to improvise. “Sissy”, meantime, take an altogether different approach to sex. She sees it as more of an act of intimacy with a partner where just knowing his name isn’t actually a sign of commitment. The question is: will he turn her into him, or might she prevail and make this leopard change it’s spots? There are a few quite potent points presented here, not least a fairly devastating critique on a modern, disposable, society. Sex for “Brandon” is just a form of entertainment. It means nothing to him and most likely to the vast majority of his partners, and to be fair to Fassbender he quite successfully brings a certain detachment to his bedroom activities. In many ways he symbolises whole generations of social media types whose best friends are folks they only know online and whose sexual experiences are either digital or transactional. It’s a film about the ultimate commitment-phobe. Mulligan injects some colour into his monochrome life, and it’s clear that she is there to suggest that some sort of emotional connection is as sexy as the sex, but even her role is unnecessarily sexualised - I felt, anyway, and her dialogue banal. It’s a slightly less seedy version of a “Fifty Shades…” book that presents many urban-dwelling humans as little better than insects venturing from their nests in the morning for the mundanities of their day then heading home for some food, some breeding and some sleep. I got the message quite early and just lost interest, sorry.
