Unfortunately, the last part of Harry Potter have not the magic of the first. The characters look like in real life: a lot of tension, a Ron who turns away from his friends, people with hardened facial expressions and little smile. Maintenance people show how difficult and "unjust" life is. ... It's like me on the job: I do not find that entertaining. For a socially critical film too much on the surface, for a fantasy film about a few miracles and for entertaining up even limited use. The director and the writer, I would have advised more "beautiful spells" and a bit of humor. To illustrate tension and threat need not be all gloom and only Dolby sound.
