It is a very good movie that fans of previous HP movies will find enjoyable, fun, and exhilarating. Strict adherents to the books will find some plot points missing or altered, but honestly, the films and the books MUST be looked at as two separate entities, and this film must be compared to the other HP films, and not the books.
That in mind, I think that the latest installment is invigorating, fun, and follows up the previous movies quite well. I would say it most closely resembles the vision the director put forth in the 5th film, which is natural, as the director is the same for the 5th as well as the 6th.
In short, if you liked the other Potter films, you'll like this one.
