I'm a huge Zack Snyder fan. The film was brilliant, and kind of had all the tones, sound, and themes of all of Zack's movies from Sucker Puncher to 300 to MoS to BvS.
I do however think Steppenwolf could have fought more (especially against Superman) and kind of missed the chaotic wild fights of MoS and BvS.
But Zack is a genius and that's probably one of the best Superhero movies ever.
