Obviously, that’s not every detail of Crisis On Infinite Earths, but it hits the major stuff the same way the Flashpoint storyline did in The Flash.
While disappointing, I don’t think The Flash is financially capable of pulling off such a tremendous event in a way that pleases audiences, and I’m sure none of us want to see Barry Allen actually killed off in the series, anyway!
Many of the details left out of Flashpoint simply wouldn’t have made sense in the Arrow-verse, so they reworked it, and I think it’s fair to speculate they could be taking the same approach here.
The two main elements holding these two Flash events together reside in Barry entering the Speed Force to save the world, and Wally West taking over the mantle as Earth-1 Flash until further notice.
