[Kevin] Spacey is very good at playing the bad guy; [but] as Hunt's life unravels, so does the movie, though the story maintains a certain baseline of interest just by virtue of being sordid
the specifics of Hunt's crime remain shrouded in mystery, and "Billionaire Boys Club" transforms them into pulp. It’s intermittently engaging as a B-movie, but so often strives for something more that it never finds a satisfying tone
it's a derivative bore, all popped collars, douchey bros and hand-me-down psychology, that gets its characters up to their necks in borrowed money just long enough to have it really hurt when the accounts run dry
