Tacking "IMO" at the end of that utterly ridiculous statement doesn't make it any more valid as a criticism of TDKR. Catwoman was one of the WEAKEST elements of TDKR as little more than a "f the 1% - selfish, Robin Hood - #OccupyWallStreet - action girl" pastiche. Her presence did more to detract from that film instead of adding to it, and actually did the mythos of the Catwoman character a disservice.
Conversely, what some would argue are key story elements, like the motivation and backstories of Cap's merry band of superpowered friends is left completely to the imagination of the viewer that hasn't seen the other Avengers movies outside Cap's trilogy. You can't keep handwaving that as a story fault when you keep insisting on judging the films exclusively on the merit of their own content.
That is part of why Nolan's trilogy is superior. He quite intentionally crafted a story that was meant to be finite, self-contained, and internally consistent. Of course, some feel that as much as that helped Nolan's movies it screwed the rest of the DC cinematic universe, but that's an entirely different conversation.
