You bring up an interesting point here about the right crew member to blame for a bad performance.

Roles/positions on a film crew seem very defined. That being said collaboration is so key.

Yes, it's easy to blame Vince or any actor giving a bad performance for seeming to miss the mark with their character.

But the director is also responsible in some respect because they approved the actor's take on the material.

Maybe the writer's vision was nebulous? That could lead both the director and actor going off in a direction that left the audience disconnected from the story.

Understanding film production is so mysterious to me. I don't know enough about it to form a clear answer about acknowledging the problem.
