Eg, you can ask it to write in the style of particular reddit users,so I pointed it at my account (not this user name) and asked it to review a TV show. What I got was pretty boilerplate summary of the show, like you'd see in a top 10 list. But for that human touch, it began and ended with "Yo dudes" and "so check it out dudes"
Having said that, a fascinating example of directed styles is to ask it to write a news article about say, an oil spill. And to either promote or criticise the response of the company.
