Compared to Justice League's Steppenwolf, the main villian is a bit more fleshed out. What doesn't help is, that his motivation and plan are super dumb if you think about it. The execution also doesn't make much sense.

The story is full of cliches and non-sensical plans and most dead people surely will return soon again. This movie is 90% CG, some of it very bad and I could believe of even the soulless script was computer-generated
