Fanfictions can expand the perception of Benedict Cumberbatch's Sherlock. They can show different sides of his character that might not be explored fully in the show. For instance, a fanfiction might focus on his emotional vulnerability, which is not always on display in the original series.
Well, fanfictions often take the character in new directions. Some fanfictions may humanize Sherlock more, showing his daily life routines or his struggles with normal human emotions. This can change how fans see him, making him more relatable. On the other hand, some fanfictions might exaggerate his genius or his quirks, which could either enhance the love for the character or create a new and different view of him.
Fanfictions have a significant impact on how we perceive Sherlock played by Benedict Cumberbatch. They can introduce new relationships for him, whether it's romantic or platonic. These new relationships can shape how we think about his character. For example, if a fanfiction has Sherlock in a deep friendship with a character from a different genre, it can show his adaptability. Also, fanfictions can explore his backstory in ways that the show hasn't, adding more depth to our understanding of the character.
