Lupin in Prisoner of Azkaban is one of the best characters in the series

I'm surprised more people don't talk about him he was one of my favorite characters in the series. His intro was so good and the mysteriousness surrounding his character made him so interesting imo. Also I really loved how he was never fazed by anything and always had an answer for everything. He was kind of like a younger, more down to earth Dumbledore. Also he was the best mentor to Harry and he was the best Hogwarts teacher overall. And I'm only referring to the book version, the movie portrayal just doesn't have the same laidback sage aura as the book imo.
