I know DC is rocking the silver screen with their storylines but there is one simple reason why they shouldn't connect it to the cinematic universe, just take a look at this,
Look at our barry Allen below, look at the costume , look at this skinny guy.
DO YOU THINK THAT HE CAN FIGHT FREAKING HENRY CAVILL, the man of steel or FULLY BUFFED UP BEN AFFLECK? I'm pretty sure he will look like a fanboy with a cosplay next to the golden trinity.
SO PLEASE STOP FREAKING ENCOURAGING DC AND WARNER BROS TO CONNECT THE UNIVERSES. It ain't gonna happen!
