User blog comment:Basit5/Why Grant Gustin is Perfect for ‘The Flash’ Movie/@comment-1038387-20160519145116

The movies and the series are wholly different universes. Casting the same actor as both would just confuse casual viewers. "Replacing" isn't as simple as you make it sound. What makes you think Miller will let his contract be bought off? This could be his big break.

Grant Gustin is nice as the Flash. Ezra Miller hasn't had a chance to show us much yet. Have patience. He may knock it out of the park.
