That is your choice and you are entitled to it. I, for one, can't stand egotistical, self-important people and it's hard for me to shake that most of the time. Would you be willing to tolerate a bad attitude from your doctor, insurance rep., co-workers, kids, etc.? If not, why would you be willing to overlook it in an actor, regardless of how "good" he is? Again, you have that right and can patronize whomever you choose. At the end of the day, though, it's that kind of attitude that creates self-important monsters. Until they learn that behavior will not be overlooked or excused, it will continue to spread like an infectious disease.
