copyright law has been pretty goofy for a pretty long time now

> The Conan Doyle Estate filed a lawsuit against Netflix over [Enola Holmes (2020)], claiming it violated copyright by depicting Sherlock Holmes as having emotions. They argued this aspect of the character did not fall under the public domain as he was only described as having emotions in stories published between 1923 and 1927, and the copyright for the stories published in that period still had not expired under copyright law in the United States.

This was a nuisance lawsuit, and Netflix only settled to make it go away. They would've crushed the Estate if it actually went to trial.
