If you don’t think it’s the best harry potter Book/movie, you are either wrong or lying. It perfectly bridges the gap between baby and teen Harry and his friends, and it’s the closest Michael Gambon has come to actually acting like Dumbledore. We get to see some of the most iconic moments of the entire series, including Hermione punching Malfoy and “EXPECTO PATRONUM!!!” Gary Oldman, David Thewlis and Alan Rickman shone as Sirius, Lupine and Snape in a film where their history was at the fore. Also, Harry’s anger is at its peak here.
