Pia Postman's character
The character came off wayyy too phony; she tried too hard. I know that was the point, to make her seem stuck-up and falsely-friendly, and it did. But she came off as plastic, even in that role.
You'd think she'd know enough to stop pecking at Frank and trying to convince him in that talk-show voice of hers.
That said, this film was incredible. Kept the tension pounding to the end.
"Some laughed. He let them. His own heart laughed, and that was enough."
