So it doesn't even have to be bad acting, only from the first person's point of view.But if someone likes the bad acting, then that makes it good from their point of view.

Acting: Does the actor look frightened? Depends on when you think it looks frightened.
Did the actor memorize at least 77% of the words in the text? 77% is not an opinion, so either yes or no.
Should the actor have spoken two seconds earlier, for a more dramatic effect? Depends on how you feel towards drama and climaxes.
Could the actor have divided his attention more equally among the other people (by looking at directly at them)? You can measure the time he looks at someone else, and of each of those people individually. If those times are too unequal, then yes, the actor could have done that. But of course, it depends on your opinion when you think something is equal 'enough'. 40/60 %? 30/34/36 %?
Or absolutely equal, 25% among all of the four others?
This makes it too damn hard to decide whether something, that involves opinions, is good or not. Even if 90% of the people agree on one thing, it shows that it's not necessarily the truth. Of course, it differs if you think about what you think is true. Like, ''does God exist?''. We have no proof for either yes or no, but I go just go with no. It's not an opinion if God exists, it's what you believe. =|
Oh well, it was mainly about the first paragraph. The last one was just an addition about people's views
