We watched Rebel Moon last night. My sister enjoyed it, I didn't, it annoyed me.
First of all I had the feeling I was missing information about the world, the war, etc. Then It was obvious that the writers just picked and mixed things from other sci-fi and fantasy franchises and mashed it all together. I also found the editing choppy.
What annoyed me most was the ending, where there was a big continuity error, which had me yelling at the tv.
