. ''Arrow'', which normally aired on Thursdays at 9pm, moved to Monday at 9pm for the crossover and did not air an additional episode on November 30. Pedowitz stated that they decided to have the crossover occur over two nights, as opposed to the four nights of "Invasion!", because ''The Flash'' and ''Legends of Tomorrow'' were already paired together on The CW's schedule, and "it would be better and tighter in terms of storytelling to make it like a two-night, four-hour miniseries. We thought this was a tight, concise way of doing it". Guggenheim added, "We're really approaching this big four-part event as two back-to-back two-hour movies, and I think when you look at it through that lens, it becomes less important for the ''Supergirl'' episode to feel like a ''Supergirl'' episode and the ''Arrow'' episode to feel like an ''Arrow'' episode, which was always our approach in the past". Guggenheim tried to get "Crisis on Earth-X" released as some kind of "single, seamless, no act breaks" movie, with the possibility of even shooting up new footage, though this was not possible due to union rules.

reported a 93% approval rating, based on 14 reviews for the episode. The website's critical consensus reads, "Kicking off an Arrowverse crossover event, "Crisis On Earth-X, Part 1" offers viewers a fun outing with quirky characters preceding the action and tragedy to come." Schedeen gave the ''Supergirl'' episode an 8.1 out of 10. While he felt that the ''Supergirl'' episode "clearly isn't in much of a hurry to get where it's going", Schedeen said it did "prove to be a very entertaining start to the crossover." Ultimately, the episode "did, however, make the most of this massive pairing of heroes, delivering an endless stream of banter and character drama before transitioning into an epic battle royale. There are certainly worse ways to kick off a crossover." Caroline Siede at ''

'' gave the episode 4 out of 5 stars, stating, "I was wildly impressed with the storytelling ambitious 'Crisis on Earth-X' has shown so far. There were some narrative missteps, but this is like nothing we have ever seen on-screen before: a true comic book-style crossover event that ties hours of superhero serials together in one epic story."


''Arrow'' episode

Rotten Tomatoes reported an 89% approval rating, based on 9 reviews for the episode. Schedeen gave the ''Arrow'' episode a 7 out of 10, saying that the episode "struggled to find that balance between character drama and plot progression, as well as in establishing stakes big enough to support such a massive crossover in the first place. But for all its flaws, at least this episode still included some entertaining moments and a generally strong portrayal of its twisted villains." ''The A.V. Club''s Allison Shoemaker gave the episode a "B" rating. She thought it was "difficult to judge how successful this episode of ''Arrow'' is because it's neither an episode of ''Arrow'' nor a complete story," but concluded, "it's a lot of fun, kind of dumb, and just not as exciting as what came before. Someone has to check those boxes and set up what comes next, and it seems that this time, ''Arrow'' drew the 'event' short straw."


''The Flash'' episode

Rotten Tomatoes reported an 89% approval rating, based on 9 reviews for the episode. Schedeen awarded ''The Flash''s episode a 9.2 out of 10, noting that while part 1 had "a slow start" and part 2 gave "a fairly underwhelming follow-up... the crossover finally seemed to click" in part 3. Scott Von Doviak at ''The A.V. Club'' gave the episode a "B+" rating, stating "Even a lesser installment like this one features the spectacle of the Flash and The Ray battling the Red Tornado, as well as the appealing non-superpowered Nazi-fighting team of Iris and Felicity. For the most part, I've felt like a kid coming home with a fresh stack of comics, and I can think of no higher praise than that." Mike Cecchini of ''Den of Geek'' gave it 4 out of 5 stars. He wrote that while mirror universe Nazis' don't make for the most nuanced of villains, and when you're using concentration camp imagery, well, you'd better make sure you're not being exploitative," ''The Flash'' episode "completely embraces its lunacy in ways that I don't even think those first two chapters dreamed of."


''Legends of Tomorrow'' episode

Schedeen gave the final episode an 8.5 out of 10 rating. The episode "didn't have quite the urgency it needed during the final showdown between good and evil," but "did make the most of Professor Stein's heroic sacrifice and its emotional fallout." Oliver Sava of ''The A.V. Club'' gave the episode an "A" rating, stating "No piece of live-action superhero media has captured the feeling of a comic-book crossover event like ''Crisis On Earth-X''. With a huge cast of characters, a major death, and a final scene taking big heroes in bold new directions, ''Crisis'' delivers the thrills, the twists, and the inspiration that should come from a superhero story with this massive scope." Jim Dandy from ''Den of Geek'' rated the episode 5 out of 5 stars. He wrote, "This year's was an objectively wonderful hour of DC television, but it also moved the season's story along for ''Legends'' in a meaningful way, and provided significant character development for Jax and Sara. It gave Franz Drameh and Victor Garber a chance to stretch their acting wings, and it closed out a timely, wall-to-wall entertaining four hours of television." ''Collider''s Carla Day gave the ''Legends'' episode 5 stars out of 5, saying the crossover was "leaps and bounds better than any of the previous crossovers." She went on to say that "It set the standard high for all future crossovers in the story, character interactions, and fight scenes."
