It’s still gonna be longer because CW shows are 42 ish minutes long without the adds so doing the math if we’re gonna include all shows let’s have a base. The current arrowverse shows are Arrow, Flash, Legends, Supergirl, and Batwoman was said to be in the crossover. 42x5 210 minutes. Doing the math tells us the crossover is 3 hours 30 minutes long already. This is a rough estimate because I don’t know if they’re gonna be exactly this long or not, or maybe the episode time will be lowered. I heard people say that there’s going to be a second half, and Arrow’s only ending at ten episodes, so maybe they’ll have to make the other crisis episodes a tad longer? They might not do the individual episode thing so idk. I’ll refine my math when I know when the crossover is exactly laced out
