This review may contain spoilers. I can handle the truth.
Not all that bad once it got going, but dear lord did it take a while to get going.
It was also a little distracting that Ravenna's brother was never mentioned, and seems to have never existed. Also, didn't Ravenna state in the first film that she killed The Huntsman's wife? In this film, she was completely unaware of the wife until the end.
I've read elsewhere that the lack of Snow White was a problem for them, but her presence in the background is what started the main story, so don't see that at all.
