The DC slate is absolutely packed to the brim with some awesome films, but few have us more excited than Flashpoint. Essentially Justice League 2, the The Flash's movie will offer fans a glimpse at an alternate reality in which Barry Allen's decision to prevent the murder of his mother completely warps the DC heroes into something dark and terrifying. There is a lot of potential for great storytelling, but there are still a few key aspects of the Flashpoint lore that need to be respected when the Flashpoint movie hits the big screen.
Although Superman and Wonder Woman (and indeed every member of the Justice League, in their own way) embody hope, Flash is arguably the hero who represents humanity at its best. He is an eternal optimist, a selfless hero and an example of what a seemingly average human can do when greatness and godlike speedster abilities are thrust upon him. Flashpoint is a story that epitomizes that idea, and the film needs to juxtapose Barry's own sense of idealism with the terrible world that he creates when he tries to go back and save his mother from Eobard Thawne.
This one may seem like a no-brainer to people who know the Flashpoint storyline, but that doesn't make it any less valuable. Although Barry's circumstances are technically the central conflict of the original Flashpoint storyline, Eobard Thawne is still the principal antagonist of the story. With no Reverse-Flash (or Professor Zoom, depending on what they call him) established in the DCEU just yet, Flashpoint will need to set up the fact that the yellow-clad speedster murdered Barry's mother. From there, the film can make him a mysterious force who taunts Barry from the shadows until his real motives come to light.
