This could have been a really great solo Flash story given that The Flash has become a supporting character in his own show but no they had to give us two more annoying sidekicks because Grodd forbid Barry handles anything on his own.I'm not even sure about the ending which seems like a fan grab more than anything else.Also when Gideon announced there were over a million changes to the universe Barry just sits back in frustration.I thought Barry was a speed reader.He can read a million words a second.Just read the list at super speed and get caught up..
