"Something isn't right."
"Something doesn't feel right."
Two highly similar statements that have drastically different implications. One brings a level of certainty while the other brings a level of uncertainty. Humans take comfort in certainty by nature. Even when an outcome is bleak or unfavorable, if it is certain then measures can be taken to come to terms with it. This in turn provides some semblance of relief. Conversely, humans find a lack of certainty discomforting. Uncertainty can turn even the most joyful occasions into trepidatious affairs. That nagging feeling in the back of the mind prevents someone from fully enjoying themselves.
From a story-telling perspective, the latter statement provides for a more intriguing experience. If the viewer knows something is off, even if they don't know what that "something" is, then it becomes a question of
when that issue will be addressed. In some instances this may even cause the viewer to become impatient and lose interest if the matter isn't acknowledged in a timely manner. If the viewer only
feels like something is off, however, then the question becomes
if the matter will be addressed, or if the matter even exists in the first place. This causes the viewer to constantly reevaluate their understanding of the situation and, as a result, keeps them engaged in the story. This is the state that
Classroom of the Elite maintains with its viewers.
