The Huntsman: Winter’s War (Blu-ray release 2016-8-23) is both a prequel and sequel to Snow White and The Huntsman (2012). We see the origin of the huntsman, his wife, and the queen of snow. The magic mirror from the previous movie has been stolen, the huntsman is ordered to recover it and deliver it to the sanctuary. Snow white is nearly completely absent from the movie, which is not a bad thing.
This movie received generally bad reviews. Other than a lack of chemistry, romance that does not work, action that is mostly average, and comedy that does not work, I do not consider the movie to be very bad, because as an impossible sequel to Snow White, the story is actually not that bad. Its quality is nowhere near Frozen (2013), but its dark alternative of the queen of snow still has some value.
Note: Unlike the theatrical edition, this extended edition does have an additional scene after the credits.
