The Crossover To End All Crossovers
Every year, we keep wondering how in the multiverse the writers are going to top the previous crossover. We said that about 2016’s “Invasion!” and then they brought us 2017’s “Crisis on Earth-X.” And following that, we got “Elseworlds.” This time, though, we’re pretty sure there’s nowhere to go that’s beyond “Crisis On Infinite Earths.”
The comic book arc is seminal for a reason as it was one of the first massive, multiversal stories that’s rarely been matched in the decades since in terms of scope. So, maybe part of the reason for doing “Crisis” next season is so that it can act as the last of the multi-part crossovers that span several shows?
Star Stephen Amell has come clean in the past to say that they’re incredibly difficult to produce. Cutting Legends out of “Elseworlds” was presumably one way of reducing the amounts of plates that need spinning, so perhaps the crew have decided that they can’t keep making what are essentially movies in the middle of the season and want to go out with their biggest one yet in “Crisis”?
