The movie wasn't inherently bad. GCI was great, I love Steampunk in generel, so the visuals were really good. But that's about the only positive thing I can say about the movie.
The plot was confusing, I felt there were huge chunks missing. At first I thought this might have been based on a book and they just did a poor adaption but it's not and it was just poorly written.

[spoiler] So Abby just got to know she knows magic, and.. just accepts it? Wants to learn how to handle her powers? She wasn't surprised at that revelation in her life?[/spoiler]

The acting and directing was mostly subpar as well and I couldn't really connect to the characters in emotional scenes.

There was a lot of unused potential. If you have 2hrs to spare, and want to watch a movie with a confusing plot but still some great visuals, this might be for you.
