Definitely an improvement over the Whedon version and as a DC fan, enjoyed plenty of the character moments (and the addition of MM) but the story did feel off even though the film is nearly four hours long, in addition the alternate timeline part at the end felt tacked on and unnecessary. The visual effects looked like something from a video game but I can forgive that since I'd imagine it'd cost an additional $100M to make it look cleaner and more realistic.
Given what Snyder had to work with and the fact in reality the studio should've been patient and given him and his family to mourn and re-group later, I am glad this did become a reality, shame that outside of maybe The Flash movie there won't be a follow-up with Darkseid. 3.5/5
