Although a lot was promised in the trailers, it falls short of those promises in the movie. Having said that, this movie is much like Deathly Hallows Part 1 in the sense that it does not stand out when watched in isolation but understandable in the greater scheme of things, as it sets up the future movies perfectly without offering much on its own.
The acting did a good job although the script doesn't allow for anyone to standout apart from Johnny Depp, who seems to make audiences aware of the fact that he's Johnny Depp every once in a while.
Overall, I feel this movie will be better received when its sequels come out, but mediocre as it stands.
