Like other people have already pointed out, if your looking for the same old story just rehashed into a new movie with different actors, then you may not like this film.
However, if your looking for a new take on an old story that have been told countless times already, then you may enjoy this movie. I personally thought this was a very entertaining movie. There was some interesting ideas in it. They follow the Snow White story enough that you recognize the characters and the overall basic ideas are still there. They however stray enough off of that story to keep things interesting to the point you do not know EXACTLY what is going to happen like you usually do in this type of movie.
As always, watch the movie and be your own judge. Don't let the negative reviews on this website keep you from enjoying this movie if you have an interest in it.
