Other issues besides parent-child
This film hits home about many aspects of family relationships, and so much more as well.
One thing that moves me is the portrayal of someone who is a hero to many, but impossible to deal with on a daily basis. With both relatives and friends, I've lived this scenario. It's difficult, because their public image is so good that saying a doubtful word about them makes you the villain.
Happily, I've never dealt with someone perceived as wonderful by outsiders who is *quite* as unpleasant as Tom could be at his worst, but I know several people who have.
The various reactions of the other characters to Tom -- his daughter's bitterness and distancing, seeing only his harsh side, his son's mixed emotions, others finding him noble and attractive, are very realistic.
I love Gene's wry reaction when his fiance says "I think he's charming."
