You know for all the flaws BvS had, the action was incredible. Say what you will about how the third act was a big CGI mess, but the title fight and Batman warehouse fight made up for it. SS doesn't have any fucking decent action set piece. Shitty writing, shitty editing, shitty motivation. I can look pass all of that if the action was at least decent.
The movie was great. was kinda slow at first, but the pay off was definitely worth it. 9/10 overall.
The opening seems to be just right. Don't know why everyone was freaking out.
