I seem to be in agreement with the general consensus. It was fine, I'm glad I watched it. But it could have easily shed 45 minutes from the run time, regardless of how beautifully shot it is.
I thought Pesci was great, Pacino pretty good (Hoffa's character could handle Pacino's overdoing it). DeNiro brought nothing to the table. The aging stuff was awful IMO. When Pesci calls DeNiro "kid" at the gas station it's a laugh out loud moment. And while they were decent about deaging their faces, they still always looked older than what they were supposed to be, and their bodies still moved just like guys in their 70s. Pacino is supposed to be 49 years old when he gets up out of the chair at his house to walk away. He looks every day of 80. DeNiro's shoulders are hunched and his back rigid all the time. And the grocer scene is just embarrassing. If this were unknown actors and director, we'd be hearing almost nothing of it and the reviews would be poor, IMO.
