Flash can go back in time to fix his mistakes. Lucky him.... because You will never be able to go back in time to fix the mistake of wasting 2 and a half hours of your life you'll never get back watching this disaster of a movie. There's so much to say, but I can just sum it all up with, it's a disgraceful interpretation of The Flash and what makes him a great character.
The CW show sadly blows this version of the lead character away. Ezra Miller's over does every scene he's in. One Ezra can be can annoying enough. 2 is just torture. Especially younger Barry. Quite a missed opportunity by DC. A total failure.
