A far cry from HBO’s other youth-centered show (that would be the visceral and brazen “Euphoria”), HBO’s newest attempt at catching the Gen-Z zeitgeist, “Industry,” hews closer to the short-lived “How to Make it in America,” both in treating the professional and sexual lives of 20-somethings as semi-interesting dramatic fodder, and in terms of quality, as the two shows are (or were, in the case of “America”) workmanlike and, ultimately, forgettable. Tracking five recent college graduates as they navigate the high-stakes financial world in London, “Industry” is hyper-specific in showcasing the trading floor, no surprise given co-creators Mickey Down and Konrad Kay previously lives in finance. But if the characters are interesting when they are yelling banking-jargon across the room from each other, they remain thinly sketched outside of the office, leading to an interchangeable roster of attractive actors, falling in and out of bed with each other, with little to no stakes.
