Man of Steel isn’t that bad. It’s not great, but it does have good aspects.
I’m surprised you liked BvS more than Justice League though. BvS was simply one of the worst films I’ve seen in recent memory. JL ain’t great either, but at least I didn’t want to kill myself while watching it.
It might have helped that I’ve only seen the director’s cut, I dunno. From what I’ve seen of the differences between that and the theatrical, I don’t understand how the theatrical was comprehensible in any way.
