Is the Harry Potter TV series worth looking forward to?

As Harry Potter fans, the biggest concern is usually, “The films are already classics, so what else can a TV series do?” Still, the series’ biggest advantage is its runtime. 8 episodes leave room for characters the films had to cut, like Peeves, as well as more complete scenes from the magic classes. And with HBO behind the production, its quality is assured. For our generation, watching a new Harry Potter grow up also feels like an extension of our youth.
