I might be past the point where depictions of sex can shock me, but honestly, seeing a naked Michael Fassbender having encounters—whether in bed, under the shower, or elsewhere—didn’t really do anything for me. His character, “Brandon,” is an office worker in New York with a preoccupation with sex, working alongside a group of men who are constantly aroused and overseen by his married boss, "Fisher" (James Badge Dale), who shares some characteristics with a rabbit. Brandon has no trouble attracting women or paying for their company until his sister, “Sissy” (Carey Mulligan), shows up unexpectedly. He’d been avoiding her calls, hoping she'd go away, but he’d forgotten that she had keys to his place—and once inside, she wasn’t in any hurry to leave. This naturally puts a stop to his lifestyle of open indiscretion, and things become uncomfortable and even dangerous as he tries to cover up. Meanwhile, “Sissy” has a very different perspective on sex; she views it as an intimate act with someone you're connected to, where simply knowing their name isn’t necessarily a sign of commitment. The question becomes: will he transform her into someone like him, or could she influence him and change his ways? There are some significant ideas explored here, including a sharp commentary on our throwaway society. For “Brandon,” sex is just another form of entertainment; it holds no meaning for him or most of the people involved. Fassbender does a good job conveying this lack of emotional investment in his sexual encounters. He seems to represent an entire generation of social media users whose closest relationships are with people they’ve only met online, and whose sexual experiences are either digital or purely businesslike. It's essentially a film about someone who is terrified of commitment. Mulligan brings some vibrancy into his otherwise dull existence, and it’s clear she’s meant to illustrate that emotional connection can be just as alluring as physical intimacy—although I felt her role was also overly sexualized, and her lines were fairly unremarkable. It's like a toned-down version of a “Fifty Shades…” novel, portraying many city dwellers as little more than insects leaving their homes in the morning for the routine tasks of the day, then returning to eat, reproduce, and sleep. I understood what it was trying to say pretty quickly and just lost interest, unfortunately.
