Things happen, then they didn't happen or didn't happen the way they were meant to happen and the whole thing is named after a club that plays no real role in the story anyway; best to sit back and enjoy the old familiar cliches washing over you.
Opening with the brutal murder of Costello by a gunman working for Genovese, only to have it revealed that Costello didn't actually die as the bullet bounced off his skull, the story then bounces around in similar fashion filling in the backstory in piecemeal fashion, at times narrated by an older Costello years after the fact.
The pair grew up as friends despite their markedly different worldviews - Costello was a dealmaker who flourished during Prohibition, while Genovese was a thug who was only interested in collecting, not investing - so when Genovese fled the country to avoid a murder rap he left Costello in charge as the boss of bosses.
Bad move: WWII broke out, Genovese was stuck in Italy for the duration, and by the time he came back there'd been fifteen good years under Costello's rule and a lot of the mob didn't want Genovese back in the top job. Costello tried to fob him off with a piece of the pie, Genovese wasn't happy with that, then when his whirlwind marriage went sour Vito's wife (Katherine Narducci) named names in a divorce court and suddenly a big fat spotlight was on Costello.
If there's a theme here it's that sunlight is the best disinfectant, as the more the media and government focuses on the mob the tougher things get for them. You're damned if you plead the fifth, you're damned if you don't.
Running parallel to that is Costello's constant efforts to placate the volatile Genovese even after he tried to kill him, making this feel like a gangster movie where one of the leads thinks and acts like he's in a different kind of film entirely. Rational thinking? From a mobster? Forgettaboutit.
The result is a story that (probably rightly) assumes we know all the gangster cliches and tropes so well there's no real need to tie things together when we all know what we really came to see: a double dose of De Niro playing mobsters who are constantly having circular conversations around topics whether they be deadly serious or wondering if the Mormons were stupid enough to only dig up one gold bible before moving directly to Utah.
De Niro himself does a good job of differentiating his two roles (helped by some relatively subdued prosthetics - Costello has the nose, Genovese has the top lip), but he's not given a lot to work with aside from Costello rarely being angry while Genovese almost always is. His characters only get a couple of scenes together; as an acting partner, De Niro makes sure to never overshadow himself.
But look, you don't care about any of this. You're here to see De Niro play gangsters one more time, and it's just as much fun now as it ever was. Sure, it'd be nice if it was in a film that added up to something, but his performance is worth the ticket price on its own - and during the final act, when this finally finds its feet and gives us both a solid barber shop wacking and a big scene where mobsters flail about like clowns, it even manages to become a solid mob film in its own right.
