the character of Mary Beth was too overdramatic
I hated how she would put her arm out to "distance" herself when faced with dealing with a situation she did not want to deal with. For example, when her estranged father was trying to talk to her once, and, when the military official came to notify the family that Harvey Jr. was missing.
I know we all have people we don't want to deal with or things we do not want to hear, but, really, who does that? This is just my opinion, I thought it was stupid.
