The Art of the Crossover: How Grey’s Anatomy Beat DC and Marvel at Their Own Game

If there is one clear mark that comic book media has left on the television landscape, it’s the crossover episode. Superheroes interacting with each other is in the very bones of comic source material, and bringing the audiences of different shows together to watch the characters interact is an easy marketing ploy that—if well executed—is appreciated by fans. It’s been used to good effect both in the CW’s DCTV series as well as Marvel’s Netflix properties. And yet surprisingly, the shows that offer up the best examples of this are not superhero series at all, but the long-running Grey’s Anatomy and its much younger spin-off, Station 19.
Since the first season of The Flash aired in 2014, the CW branch of DC Comics shows have been known for their yearly crossovers, and while they are always an all-out affair, it would be inaccurate to say that they don’t have their flaws. When the first Arrow/Flash crossover aired in 2014, it served as a great way to further establish the story universe Oliver Queen and Barry Allen shared. Having Team Arrow and Team Flash interact with each other created an untapped well of potential for closer relationships to strengthen the connection between the shows. There were smaller moments dispersed through that season of The Flash where Oliver, Felicity, Laurel, Ray Palmer all crossed over for one-off episodes, and if moments like that had continued consistently as DCTV expanded on The CW, we would have gotten to see an incredibly rich shared universe.
Unfortunately, this level of cross-show interaction drastically decreased as time went on. As the multi-episode crossover events started to get bigger, they weren’t getting better. The relationships between the characters on different shows became less and less believable. At best, the majority of these characters were minor acquaintances, and while that works fine in a fight scene, it made for weak interpersonal interactions. There were so many times where the bond between Barry and Oliver was supposed to serve as some sort of emotional core in these crossovers, but they ultimately failed because the two didn’t speak to each other any other time of the year. By the “Elseworlds” crossover, Barry didn’t even know that Oliver had been taken to prison by the FBI, even though that was readily available public knowledge.
Marvel doesn’t fare well either when it comes to the crossover game. While a major crossover with any of the Disney+ shows is yet to be seen, the first half of Netflix’s foray into the Marvel Universe were centered around a large crossover series: The Defenders. That series did manage to forge convincing relationships among heroes Matt Murdock, Jessica Jones, Luke Cage, and Danny Rand, but the story that brought them together majorly hinged Iron Fist’s first season, one of the weakest Marvel productions to date.
Unlike the previously mentioned DC characters, the majority of characters in the Netflix shows never had the chance to create stronger bonds with each other beyond their interactions in Defenders, and those who did were never titular characters. In the one of the greatest ironic twists of all time, Iron Fist’s second season managed to greatly improve upon its first, and a large part of that was the exploration of the friendship between supporting characters Colleen Wing and Luke Cage’s Misty Knight.
In a purely technical sense, the best elements of these crossovers combined to create a convincing shared universe, but the most important thing that a multi-show television franchise has to offer its audience is constant cross-show interaction. And this is where Grey’s and Station 19 come in.
