The best superman of the story REEVE used the red trunks.. and was and is admirated in the world.. I don´t see problems with this..
If you don´t like the trunks, maybe you are not ready to be a Superman fan... Especially now that they will return..
Meh... Batman with or without trunks, no matter... I am watching the Batman Brave and Bold serie again.. NO PROBLEM..
Batman case is a little different, the trunks seems less important than with Superman.. But if they return... WELLCOME HERE AGAIN.
