Not denying that they were flops, they just aren't listed in the Top 100 flops of all time according to Wikipedia. There are other lists I found that were very similar.
I'm sure there are plenty of male and female led flops not on the list and absolutely Elektra and Catwoman are among them. They were terribly written movies.
Steel, Superman IV, Jonah Hex, the Punisher: War Zone and the new Hellboy bombed as well, btw, but I didn't list them either.
Hell, Howard the Duck tanked and he still showed up in an MCU movie
Correct, but they didn't put a moratorium on male led movies. With the WW DVD movie, it led to 'no more female led DVD' movies for a very long time.
