Immediately, Gunn was diplomatic, saying that Marvel and DC shouldn't be seen as rivals. Sure, Marvel and DC have been vying for control of the comics market for years, and fans often enjoy heated debates about the merits and demerits of each, but the MCU and DCU, Gunn feels, complement each other rather than enter into in conflict with each other. He said:
“Frankly, I think the better the Marvel movies do, the better it will be for DC, and the better the DC movies will do, the better it will be for Marvel. […] When people watch bad movies, they don't want to spend more money to see more movies. So you want good movies to happen.”
He did, however, mildly criticize the use of a universe-wide cataclysm as seen in “Infinity War.” After erasing half the universe, how can new stories be written that can surpass it? A population reduced by half would be a mess. Gunn feels that erasing half the universe would be too dramatic to recover from, and all future stories would be about how the entire universe was driven mad by the drama. The filmmaker said:
“There was a worldwide, universe-wide event that happened. And in fact, everyone would be completely crazy at this point. […] So it's hard to write stories after that. That's why the 'Guardians' movies were easier, because they're set a little outside of that.”
Gunn's “Guardians of the Galaxy” movies take place in deep space with alien/android/mutant characters who don't interact with other Marvel heroes very often. The physical distance from other films allowed it to remain in something of a bubble.
