For those not familiar with comic books storylining styles from different producers, this is DC style. It's relying on dramatic tragedies and quick turns of events (rather than Marvel's soap opera eye-candy style).
When they described how ambitious Crisis on Infinite Earths is, they literally means ambitious. 5 main episodes, 6 supporting episodes (including Black Lightning season 3 episode 9), and drizzles of revelations throughout the seasons of the main 4 series (Arrow, The Flash, Supergirl, and Batwoman). DC's Legend of Tomorrow will be the closing, which means a 2-hour conclusion (Arrow as the first hour). That is a brave move for DC to build up such elaborate story with multiple branches and possibly after Crisis episodes. Of course, it is not as big as a gamble compared to Marvel's phases on cinemas, but DC finally brings their A games to produce trivia-episodes for years to come.
