A better directed third entry with more ambitious atmosphere, visuals, story and editing. The actors has also become better and literally grown up acting-wise. Michael Gambon is also a great replacement for Dumbledore. It is all very good until the "status quo" resolution that ruins the excellent build-up of the story.
Cuarón turns in an anonymous bit of studio product. A film where once again nothing is at stake; just scenes that need to be gotten through so the series can arrive at a certain point. A non-story that can't decide what it wants to say so settles on saying nothing. Full of the usual plot holes & 'dues ex magicas', where things feel like they're being 'conjured up' whenever the writer is stuck for actual developments.
Highly regarded as "the best" film of the franchise, Azkaban pleases the eye and the mind with a much grimmer tone than its predecessors, a smart time-travel plot and important revelations from the past. Perhaps its most successful achievement is the cruel realisation that the kids are no longer kids, and that times are darker... Voldemort's absence, however, took away some of the gravitas present on other films.
In this third part of Harry Potter saga, director Alfonso Cuarón did some changes in its tone. I think it is more dark than the first two. Each characters in this movie is well-developed. They have deeper characteristic. Daniel Radcliffe knows how to make his character more alive. Really, really love the complexity of its plot and Mr. Cuarón's impressive direction. This movie is one of my favourite part in the saga..
