What was wrong with Peggy?

Huh, what do you mean, her father showed her only love...

The evil eye she gives Russell during the Christmas scene was on point though.

totally agree, she slows the film down, imo.

Her general silence for the most of the movie all builds up to the point where her father Frank mentions in quick passing that he hasn't called Hoffa's worried wife about Hoffa's disappearance yet.

Pacquin fixes her father with a stare and accusingly says "Why didn't you call?"

Frank tries to deflect her. She again asks "Why didn't you call?"

Frank gives a non-answer and then agrees to make the call.

DeNiro's narration is perhaps too "on the nose," but telling: "After that day , she never spoke to me again."

And we later SEE her abandon her bank teller job on the spot when Frank tries to approach her.

So here is a movie -- and a script -- that creates a female character in a very specific way: nearly silent except for one key phrase at the end: "Why didn't you call?"

That's when she knows that her own father killed his own best friend ...and a man she truly loved (Hoffa.)

And yet some dopey critics objected to Pacquin's lack of lines. Jeez. The movie was smarter than they were.
