Justice League: Crisis on Infinite Earths - Part One has that very similar energy to how Warner Bros. ended the DCEU and the Snyderverse. In this case, Barry Allen's Flashpoint doesn't immediately reset the DC Animated Multiverse. Instead, it's a slow burn, playing off the classic Crisis on Infinite Earths event from the 1980s with the Monitor assembling heroes to fend off an anti-matter wave.
