The first one in the series made for grown-ups and kids

Rating: 9/10 (19 November 2017)

I'll keep this review short since the movie came out more than a decade ago and it has been universally viewed. 5 movies came after this one in the series and 2 movies came before, yet Prisoner of Azkaban still remains my favorite (and many peoples') Harry Potter movie. This movie is the one of the few in the franchise that tells and completes a story. It deals with Harry uncovering a truth about his past involving his parents' murder, and explores how he adjusts to this truth. Here's what makes that sentence special: was there any mention of Voldemort in that summary? You'd be hard pressed to find any mention of him either in the movie, except in a couple sentences. This movie can be seen as separate from the rest of the Harry Potter movies because it holds up as its own, without having to build up the universe or service the Voldemort storyline at all. It's also the first movie to feature the dark undertones that the first two implied but never fully explored. He must deal with his darkest fears while also dealing with the danger of a murderer seeking to kill him. This is more personal, but this movie ironically deals with time travel better than any sci fi movie I've seen about it because it portrays it in a way that time is immutable, which makes the most sense.
TL;DR: Dark and original, Prisoner of Azkaban stands as its own movie without having to build up a universe, while also entertaining in its own right.
