Tricked by the pay reviews.

Rating: 5/10 (31 December 2018)

Film is nothing special, even Thor The Dark World, that is considered as the worst movie in MCU, is 100 times better than this. They are constantly trying to make DCEU better but they messed up with Batman and Justice League. You can't beat MCU. 5/10 is most objective rating for this movie, adressing the good and bad things in this movie.
Also, i don't understand this 10/10 reviews, and that is my reason to suspect that those are paid reviews or maybe those who review does not understand how the rating system works. Giving 10/10 you are practically saying that this is the best movie ever. Compare Infinity War with this mess.
