My issue with Julia was not that she was struggling to juggle or that she had a useless husband. It was that her solution to the useless husband was to pass all the shit on to the other women in her life and give precious little in return.
At the beginning of series one the children were nine and five and had received all their care from their grandmother, including parties, sports days, swimming etc - all of which were new to the Julia who had never had to worry about her old own DC whilst at work. Instead of paying for more help or setting higher expectations of DH, she just berates her mother for being selfish in ceasing the full time childcare. Husband, when he finally appeared. received a free pass on his behaviour beyond the odd eye roll.
Its a character I've certainly seen in real life and its very unattractive. They were usually also the loudest whiners about how hard they had it and how SAHMs such as Amanda have it all so easy (but BTW Amanda you're a SAHM so pick up my kids on Thursday). The whole "starting my own PR business" whilst apparently doing no work was just nonsense even for TV portrayals of WFH.
Obviously I'm over invested in the characters!
