Well, this movie is a bit different. So, right up front, let me say that I liked this movie a lot more than the critiques. Sci-fi and fantasy are definitely in my wheelhouse. I also enjoying watching Dane DeHaan. Kris Wu is also a nice in the eye-candy category too.
The movie's special effects are outstanding. The plot, which those critiques complained about, requires you to pay attention. Not Inception levels of attention, but not casual watching either. I enjoyed the movie enough to watch again. It's worth checking out if you like Sci-Fi, for certain.
