Over the past few years Marvel Comics has caught a lot of flack for changing its flagship characters. The title of Iron Man is currently in the hands of RiRi Williams, a teenaged girl genius with all the tech savvy, people sense and situational awareness of boiled parsley. For about a year Captain America was replaced with an evil HYDRA counterpart due to cosmic shenanigans. And, in a move that felt much like a demotion to many fans, popular characters Falcon and X-23 were shifted into the roles of their friends and mentors, Captain America and Wolverine. The most galling thing for many fans seems to be the way these changes came out of left field, with little attempt to build them up in narrative or make them look like the actions of normal human beings.

In their ongoing attempt to prove they are better than Marvel at anything other than making movies, DC took their very popular CW show Arrow and took main character Oliver Queen out of the Arrow suit – at least for most of the first half of the season – and replaced him without any fan batting an eye. What happened? Why did it work when Marvel’s attempts at switching leading roles didn’t? Let’s take a look.

Reason number one is John Diggle. No, not the Anglican Bishop, Oliver Queen’s bodyguard, portrayed by David Ramsey. There’s been a natural friendship built up between Diggle and Oliver over the last five years, aided in no small part by the natural chemistry between Ramsey and Steven Amell, and cemented by countless saves in myriad life and death situations. They trust each other’s judgement, moral fiber and skills. That makes the passing of the torch from Queen to Diggle quite natural and believable.

Furthermore, while Diggle does have his own hero identity as Spartan it’s not as well established or deeply seated in the public’s psyche as the Green Arrow is, and I’m not just talking about the show’s audience. The Green Arrow is a symbol for Starling City in ways no one else can rival – though the Flash is just as powerful in Central City – and preserving the power of that symbol means someone must wear the hood. The Spartan can’t just step into those shoes. Diggle giving up his own superhero identity isn’t a random demotion forced on him by the script but rather a sacrifice he makes for his city and his friend.

Which brings us to point two. Oliver’s struggle with being the Arrow – green or otherwise – has been ongoing, a constant thread since the end of the first season of the show. This issue was forced to a head when Oliver’s son, introduced two seasons ago, loses his mother when she’s used as a pawn in a battle with one of the Green Arrow’s rivals. With his responsibilities as the Mayor of Star City added on top of his new responsibilities as a father and his son’s deep dislike for the Green Arrow persona which is tangentially responsible for his mother’s death, Oliver’s decision to step back from the superhero life is not only understandable, it’s admirable. The press to be in the thick of things weighs hard on Oliver but he’s not the right man for the job right now. His reasons for stepping back are well established, believable and meaningful, to the point where we’re glad he’s made this call, rather than resenting it.

But the biggest thing is this change let us see new sides of both characters. Diggle struggles with being in command. He’s led other people before but never been at the top of the command chain and it weighs on him. Worse, he’s struggling with the physical toll the life has taken on him and he’s going to extreme lengths to keep it up while keeping his allies in the dark. It’s a new kind of challenge for Diggle, but one we’re sure he’ll live up to. Oliver has new responsibilities too, to a son he doesn’t really know and a city he’s not trained to manage. And beneath it all is the constant desire to get back out in the field and make a difference on the personal level, something he has to hold in check for now if he’s going to meet all his responsibilities. These struggles and opportunities are new and interesting and, if they don’t have quite the impact of Arrow‘s early seasons they’re still well written and interesting and no doubt people will continue to tune in and see what happens.

Marvel’s character swaps rarely present anything interesting in terms of new struggles or new stories and they’ve come out of left field time and time again. In setting up their change far ahead of time and driving them by story events as much as by editorial mandate, Arrow‘s writing team has managed to pull a very impressive switch that has so far eluded their rivals. There’s lessons for all to be learned in how they’ve done it.
