The main complaint I’ve heard about this (and Spider-Gwen, and Spider-Woman) is basically “oh noez, they’ve got WOMEN all up in my comics!” To which I say: “heck yeah, about time.” Silk’s first solo volume is reasonable, though the themes are familiar — Jessica Drew had some of the same adjustment problems from her spidery-past, Cindy has to learn to do the whole great-power-and-responsibility thing, coping with a normal life, and so on.
It’s fun enough, though not outstanding, and somewhat hobbled by the fact that it almost immediately gets swallowed up by Secret Wars at the end of the volume. That certainly didn’t have any kind of positive effect on solo storylines (not that I’ve seen anyone being fond of it elsewhere, either). Almost universally it just suddenly happens and derails all vestiges of solo plot.
Stacey Lee’s art is great, though — fluid lines, good expressions; it works for me very well, and I hope she illustrates future issues.
