KotovSyndrom’s review published on Letterboxd:
Yeah, this is where Harry Potter started to become more. Just such an obvious step up in every way to the movies before.
To this day manages to be unsettling and super atmospheric, while also managing to have some fun between all the beginning dread and Harry's further search for his self and his past.
With Thewlis and Oldman this movie also added two of the better things about the franchise. Love their performances. The transformation of Lupin is still pretty ballsy for a movie like this.
Overall, it's just really easy to see how much of a difference someone like Cuarón can make. Much darker (which doesn't necessarily make a movie better, but worked very well for this movie), very energetic, extremely good entrance scene for the dementors, cool time travel plot that actually works well within the context of this movie, etc. The camera work was also immeasurably better.
Just a great movie.
