Marvel is doing much better than many seem to want to admit. Marvel comics always offers more comics and a wider variety of comics month after month. January/February/April/May/June/July 2017 it led in units sold and dollar shares, but so many comic book websites talk about how Marvel is failing. In March is led in dollar shares but not units shipped. The controversial Secret Empire series is still shipping over eighty thousand units in the middle of the storyline.
They don't have a single series that sells over one hundred grand a month like Batman, but rather offers a comic for everyone's preference. Since when does beating the competition count as a disaster?
