What do you and Bob Chipman mean by a soft reboot with Flashpoint? In the IT world that means rebooting the software, but not the hardware of a computer. Are you saying they should start a new series based around that episode, keeping all of the actors from The Flash show?

So, DC are planning a Flashpoint movie. In the comics, Flashpoint was a storyline in which Barry Allen uses his powers to try to go back in time and fix the timeline because someone evil has been messing with it, and in the process creates a new DC universe. 

In comics, this is referred to as a soft reboot because you’re not completely starting over from scratch, you’re just saying that some things are now different (another term for this is a retcon). A hard reboot would be saying that all of the previous comics didn’t happen and starting all of the characters over from their origins. 

So in a putative Flashpoint movie, you could have Flash go back in time and change history such that say, Man of Steel/BvSDoJ/Justice League didn’t happen, without changing the events of Wonder Woman.
