I do wonder if that ends up working in Breaking Bad's favour. Breaking Bad is very much a show that shifts between Walt's and Jesse's perspectives. Much of the naggy housewife characters could just purely be the result of Walt's perception of his wife and Marie.

He's a massive narcissistic and appears to subconsciously disregard the female members of his family. He doesn't regard Marie as anything other than a bit of a judgemental snitch and an extension of Hank who is his main rival and the man he seems to compare himself to pretty regularly.

As for Skylar, he sees her as an obstacle to be worked around and not someone he loves, necessarily. He may have loved her at one time but now he just sees her through the lense of his own status and reputation. The has been trophy wife of a business enterprise that he sold his shares in way to early.

As for Better Call Saul. The female characters have a greater amount of variety because they encounter a greater number of people. The varied perspectives of different characters reflect on themselves and the female characters to create better rounded personalities.

There's also the possibility that Better Call Saul is much more based on Saul's personality and view of other people. He's a dodgy guy but he doesn't do it out of malice or narcissism (at least not until much later).
