The BvS suit is very good in a lot of ways, but the changes for Justice League were not improvements. The JL cowl is just yuck . It has a lot of bad angles with those backwards pointing ears and the Snyder muscle suits are just over the top.
It's funny how Wilkinson knocked Batman's and Superman's suits out of the park the first time around and they messed them with tweaks the second time.
While I appreciate the DKR suit in BVS, it is not the suit I want for a younger, detective Batman.Neal Adams-style all the way. Bring back the long ears! If they want to go darker and keep a Miller-vibe, then Year One is the way to go.
