It is okay, at best.

Rating: 5/10 (14 December 2017)

I went to see the movie at the European premiere last night.
The movie spent too much time introducing new creatures and places, which in the end did not contribute to the story. This reduced the amount of screentime for actual character development. Which is nescessary when you add several new characters, and expect the audience to care about them.
In the end, the movie came out as a filler episode of a sitcom. A lot of stuff happens, but nothing of value happens. In quality it is comparable to Attack of the Clones.
