I dunno, kinda seems like a 'snyder cut' kind of complaint. We saw that she had the Darkhold and she went looking for her kids by the time we see her again she's going scorched earth to exit the reality where she has known nothing but pain and heartache and go to one where her kids were real. She looked for her kids via the Darkhold and this is what she found. Do we really need a handholding scene where she makes the decision that she can't recreate her kids but via the multiverse she can do the next best thing? I kind of hate this instinct that audiences are incapable of filling in the gaps or even worse that not documenting every single step is 'bad writing'. It's the Cinema Sins/Pitch Meeting effect where people have taken a perfectly fun exercise and mistaken it for actual criticism.
