Harry Porter and the Philosopher’s Stone & Harry Potter and the Chamber of Secrets: definitely my 2 favorite HP movies. they’re the only ones that are similar to their respective books, which matters a lot to me, and the color grading on these pleases me a lot more than that of the other 6 as well. williams’ score is superb, incomparably better than that of the rest of the series. richard harris’ dumbledore is much better than michael gambon’s, too, which makes a heck of a big difference, especially on rewatches. the special effects in the first two movies are also much better than the sfx od the other 6 - they rely a lot more on practical effects which stops the movie from turning into a CGI mess, like the recent Fantastic Beasts.

Prisoner of Azkaban is really good movie in the franchise imo, because while it differs from the book and the other 2 drastically, i like what it tries to do with the franchise. but the rest is just not as good as the first three, unfortunately.
