Details: Aired in 2017. This is a four-part crossover, television show special comprised of episode 8 of season 3 of Supergirl, episode 8 of season 6 of Arrow, episode 8 of season 4 of The Flash, and episode 8 of season 3 of Legends of Tomorrow, in that order. Each episode is about an hour-long and aired on the CW.
Ever since the CW started airing more than one DC Comics superhero show, they began to air an annual crossover episode where the heroes on all their respective superhero shows team up in a self-contained story arc and fight a common enemy. This means more special effects, more action, and more funny/strange moments between characters who would normally never interact with one another.
The crossover miniseries this year is the largest to date as it combines the cast of Supergirl, Arrow, The Flash, and Legends of Tomorrow. You’d think it wouldn’t work, but despite some cringe-y moments, it mostly does. If you are at all a fan of the CW’s superhero shows, this is the television event you should watch.
This time, The Flash is marrying Iris, his longtime girlfriend, and all heroes from all four shows are invited. Unfortunately, Nazi doppelgangers from an alternate dimension where the Nazi’s won World War II invade and our heroes must now fight an army of Nazi’s along with evil versions of some of their most powerful allies.
It’s mostly nonsense, as most of the superhero shows on the CW are, but it’s fun nonsense. A lot of the fun is watching characters on one cast hit on or hook up with characters of another cast. We get to see alternate universe versions of different characters. We also get to see some big plot events with clear consequences for the story arcs in the individual shows. It’s just a lot of fun with some funny moments, lots of action scenes, and that classic often weird looking special effects that they use on CW shows.
Overall, it was a fun time. I don’t really watch all the CW superhero shows anymore because I kind of had enough. There are too many of them and they’re kind of boring. However, I did enjoy watching this despite how cheesy and illogical a lot of the moments were. Crisis on Earth-X is flimsy fan fiction at its finest.
