Sub out Pacino for an actor in his prime then give it a re-edit to tighten things up and it's probably an 8.

Pacino was at his worst. There were some scenes were they could not hide how decrepit he is. He seem to be in poor physical condition. At times he was struggling to keep his left eye open. He was shouting all of the time. Just a miserable performance. He's a bad Saturday Night Live skit come to life.

DeNiro was better than Pacino and in good shape but they could not hide the fact that he's an old man so some of his scenes looked ridiculous. These type of roles have a high floor for DeNiro so he's always solid in them.

Everyone else in film was good. Outside of Pacino solid performances all around but the film lacked polish as if it was rushed through the editing process.
