Though an extremely simple story, it was not well told. The CGI/Special Effects were very good but should enhance the story and not be the star of it. The two humans were simply along for the ride.

Unless one is familiar with the book it's hard to get a handle on how this world works, because they simply did not spend the time needed to build it for us. The leads bonded together faster than Wolverine and Rogue with a similar relationship dynamic. The gruff, world weary, reluctant hero and the abandoned young woman with a power that frightens people.

It felt like the FL's one acting note she was given was to stand there and look pretty and forlorn. Not a lot of depth to the performance. The ML spent most of his time running and jumping which to his credit, he did well.

The CGI was very good and creative. The problem for me was that the story overly-relied on it and over-estimated how interesting it is without an emotional story to propel the characters through the monsters and labyrinths.

It's a shame they didn't spend a few more minutes developing these characters because there is an interesting story behind the wall of CGI.
