It's quite arty, like most of Aronofsky's films, so he may not be into it. I thought it was better than Requiem for a Dream and The Wrestler, so if he's seen and like either of those he may enjoy this one. While the subject topic isn't 'manly' it is a really well done film.
Or of course, you could both just roam the streets looking for hookers, cocaine and absinthe. Your call.
