Darkseid doesn't live up to the hype created in previous movies. The only scary thing here are the paradooms. Powerful heroes and villains are nefted badly while the plot armor for some others is a little ridiculous. Raven and Damian relationship feels kinda forced. Superman and Raven duo deserve more attention. Characters like Starfire, Martian Manhunter, Hawkman,... don't leave any impression. Well, can't ask more in a 100 minutes animated movie.
But yes, it is really enjoyable with almost everything that makes a good animated movie. The force in every punches, badass fights although fails a bit short, beautiful art,... Not a rollercoaster of emotions it tries to be however the ending did touch me a bit.
