So they cancelled both their Female solo ongoings, and their one LGBT solo ongoing. AND, if i'm not mistaken, there are no female writers still working as of February.
Oh... Marvel.
That's a rather unfair criticism. If Marvel puts out solo books starring women, and if Marvel hires women to write comics, and those comics are not being bought in profitable numbers, they will cancel them. If anything, this only proves they're being unsexist and fair, not giving women positive-discrimination by steadfastly holding on to some arbitrary tokenship quota of women even if no one is interested.
X-23 got cancelled because it was selling less than 25,000 copies. If people felt it was so important to have these titles, they should've been buying them.
Now, whether or not your only women solo books should be a female version of Wolverine or Ghost Rider is a completely different discussion, but the sexism implied is simply absent.
The problem is, all the boutique books are being lost, the books that might be gold star quality but only have a small devoted fanbase. Instead we get over-saturation of franchises that sell on brand name rather than artistic quality.
Yeah, they sell a lot of crap. But a big percentage of that crap is glossy garbage that sells well. Capitalism is not a barometer for artistic worth, despite our compulsion to apply a capitalist model to everything.
While this is true, there is hardly another barometer to use. The best way to discover if the art is successful, is if the artists can make a living off their work. Another avenue is to consider the audience size and see how it does in that regard (for example, a niche product like a minimalist love story will simply have a smaller audience than a SUPERMAN title, which is fine, in which case you have to judge its success by its sales in proportion to the audience's interest), which they do.
But more importantly, I sincerely doubt that these cancellations are unjustified in terms of artistic worth. Which is a shame.
