There are times that I felt really sorry for her; losing her looks, and willing to buy people for love.
Max protects and loves her, even though he thinks he is helping her, he is actually contributing to her delusions.
Joe having Betty come to the house was done more out of anger at Norma, and was felt mean to Betty. If trying to hurt both he succeeded, although I think that he wanted Betty to marry Artie, because he was such a great guy.
This movie was really well done, and I could imagine not very well liked by the Hollywood inside crowd, because it pokes fun at them and their lifestyles.
