An actress/actor maybe judged by another dependent on the day they had or their own personal experience rather then the actual talent they’ve witnessed. If someone has never dealt with a person this individual is trying to portray it might be a bit more difficult for them to see how realistic their potrayal actually is. On the other hand if someone has seen several different movies in a row they may become blended together rather then see the individual talent that is seen by others on the screen. Our experiences during the day can also foster a certain opinion of an actor that we “subconsciously” don’t even know exist. That is why we often should try to clear our mind and read a bit about the characters on the screen before the lights go out. Who knows there maybe some hidden talent that we would thrown out if only explored in the bright lights.
