So in which way it's going to be a Harry Potter TV-series, if they alter how main characters look and change the way how environment looks? And I guess Hogwarts will be pink and Hagrid will become a gnome because of copyrights again? They will get a score of around "3" on Metacritic and claim that it's because users are just toxic..
This is an adaptation of the books, not the movies. It's actually very faithful to the books so far apart from Snape's actor. The movies changed and cut out a lot from the books.
