Look, don’t get me wrong, all of the Harry Potter movies are brilliant, but the third film is unequivocally the best of the series. Here’s why:

• The music: This was the first film that successfully integrated choir music into the wizarding world. The transition between Harry looking out of the train window and the frog choir singing in the Great Hall is one of my favorite moments of the film. The song itself, “Double Trouble,” based off the witch’s song in Shakespeare’s Macbeth, foreshadows the tone of the film perfectly.

• Building the Universe: This movie lays out the world in a visual way that makes Hogwarts feel real and helps you understand that this story, while magical, is grounded in reality.

• Adaptation of the World: This movie, like the wizarding world, is dark but also really silly. There are things like the shrunken head on the Knight Bus that are added to give it this whimsical feel that even J.K. Rowling herself said that she wishes she would have come up with.

• Newcomers: This movie welcomed some of the series’ biggest stars, with Gary Oldman as Sirius Black, David Thewlis as Remus Lupin, Timothy Spall as Peter Pettigrew, Emma Thompson as Sybill Trelawney and more.

Also, classic ending!
