Stop that, it's annoying.
Stop assuming that just because I
try to quote only the core portions of why your argument doesn't work, I'm not attempting to addressing your argument as a whole...and we've got a deal!
Basically, it's easy to point a finger at 'men'
This is a viewer assumption. Plenty of people have worked to perpetuate these stereotypes, a decent number of them were women (take the whole Manic Pixie Dream Girl thing, most are usually considered romantic movies and if what comprises at least half of their target audience stopped seeing them they'd be a lot less viable). Everyone is getting called out here.
and say "You're doing it wrong!", but how many people, at the end of the day, are going to pay attention to that?
It's especially not valid when it comes to artistic criticism. Ebert's job was not to speculate on the causes of why a movie was terrible, but to tell you why it was terrible.
This deals with "art". Movies. Video games. It is artistic criticism. Eurogamer and RPS don't tell you, and typically don't even know, why a game turned out the way it did. All they can do is report on the finished product.
Now, I've read some criticisms that do attempt to explore why the work the in question is terrible. (I highly recommend Slacktivist's exploration of the
Left Behind novels if you're into that.) But they typically come from a background where the critic is well-equipped to understand the creator and the work is illuminating as to the creator's thoughts because of a specifically revealing form of bad writing, lack of editorial filtering, or both.
However in this case, discussing things across a decently long span of time and lacking the budget or the ability to track down members of the production, asking someone to identify the root causes of the issues they're discussing is unreasonable of you. It's also (again) not something that artistic criticism usually does because we're not usually interested in it but rather whether we should spend our money on this object, or should usually be required to do, because there is no guarantee that anyone in the production will talk lest they be perceived as talking out of school.
As has been evidenced in here, people see 'feminist' and move on, so even though she is making valid points, people will automatically assume conflict of interest unless some attempt is made to moderate that viewpoint.
You can't be Writing Women Badly without Writing Badly.
Going back to the Manic Pixie Dream Girl example again, in the process of making the feminist case for why it is bad you also make an excellent case that it is simply bad to create such a character in general, as their actions are inhuman and their motivations bizarre. It is only the fact that such characters are almost (or) always female that makes the criticism feminist. (Because making women act in inhuman and bizarre ways implies women are inhuman and bizarre, natch.)
The viewpoint indicates that a certain kind of Writing Badly is being addressed. A similar kind of focused on-a-particular-set-of-issues criticism can be made in a lot of ways. I could start a Militarist Criticism movement where I examine a work every week for its failure to understand military or para-/pseudo-military structure when dealing with such. Or a Policist Criticism movement. You get the idea.
Looking for a specific form of failure is specialization, and it's up to the audience to apply their own critical thinking skills when coping with any criticism. If they are unwilling, that reflects poorly on them, not on the critic.
