The phrase "reimagined for the modern age" in the solicit for an upcoming book or movie based on a classic character can only mean "Don't worry, mainstream audience! We got rid of everything unique and turned it into a rehash of what you've already seen a thousand times! You're welcome!"

Now, do you mean "Modern (as in history ca1500-1945 CE)" or "Modern (as in art ca1900-today)" or, say, "mid-century Modern"...?
