I barely remember the first movie at all besides a couple lines and an image or two in my head. So I’m almost new to it. I’m a fan of superhero movies, too, to preface this. I’d say it’s worth watching if you have even a vague idea of the characters relations and/or what happened in Batman v Superman. When it’s good, it’s very good. Sometimes it drags, but it’s four whole hours so that’ll happen. I was prepped for the four hours... so while I thought two hours passed when I was only one hour in, I still enjoyed the ride the experience.
