The announcement for the Harry Potter series was both exciting and panic-inducing. The books were magical, and the movies captured the essence (which is rare), which is why fans have a lot to lose if the series does not manage to do the same.
There is a lot that the movies missed out on, as going into finer details would take too long, and there’s only so much you can process in two hours. The series will have the advantage of more time on their hands, so for book fans, you may finally get to watch the scenes you loved in the books but never got to experience on-screen.
