I'd say that's a pretty fair assessment, and I agree with Grundoon wholeheartedly.
A big part of DC's problem is that it has a nasty habit of making their superheroes omnipotent and not very engaging; their characters are fairly one-dimensional with one of the more prominent exceptions being Batman, which is why movies depicting him usually are so successful. Likewise, he is the only one with engaging villains; it's the opposite of almost every other superhero wherein the hero is the colorful, chatty one with villains being taciturn, dark, and brooding. That being the case, members of the general public who may not be comic fans outside of the movies generally aren't familiar with many DC villains outside of Batman, save for Lex Luthor. For instance, I grew up reading Marvel and some DC, but I haven't seen the Wonder Woman movie (yet) and never read her comics - I don't think I could name one of her villains if my life depended on it.
Marvel, on the other hand, has fleshed-out characters who have human characteristics and can be somewhat more relatable. It helps that they can be vulnerable, which adds to the drama, and humorous, in addition to having a lot of action. DC films seem as if they are trying too hard to be gritty, devoid of any light-heartedness.
Maybe DC should get people who are actually fans of the comics and characters they are depicting to direct.
