Marvel movies are great. We love them. One thing you can't really deny though is that over the course of the last ten years the franchise's powers that be has found a narrative formula that works for them and stuck to it. There's very little narrative difference between Iron Man, Ant-Man, and, say, Doctor Strange. They all follow the same general sort of plot and story beats.
The DCEU, on the other hand, has given their directors a bit more freedom to break away from a formula over the course of their films. This isn't to say that they don't follow familiar beats or a standard three-act structure, but the way the films play out doesn't feel nearly so rehearsed or predetermined as it does in a Marvel film. In fact, the one that feels the most formulaic is Justice League, which is the one that most clearly tries to replicate the Marvel formula. You could chalk that up to the MCU being more than 15 movies into their universe while the DCEU is less than ten. Nevertheless, it's a noticeable difference and something that, at the least, makes the DC films more compelling in their own way.
