The movie serves the purpose that the title stands up for. We did discover new things about Dumbledore, like his sexual orientation, the fact that he knew who credence was since the beginning, etc... However, I think that I speak for other fans as well as myself when I say that more action was expected especially by the end. In terms of narrative, the climax, and the resolution part finished pretty fast, not matching our expectations. In a nutshell, I would say that the movie is good, only my expectations for it were higher. Enjoy!
