I've said it before, the Alien films having female leads doesn't bother me, and I'm a dude.
The franchise kind of relies on the ensemble cast anyway. It's never really just Ripley or Shaw, etc. The lead almost changes by the moment.
The character balance is truly excellent. Plus, the male roles have hardly been lacking. Hicks, Hudson, Clemens, Dillon, Parker, Dallas, David, Andrews, Ash, Apone, etc. Even the avp movies and Resurrection had plenty of strong male characters. Us dudes, have been well represented.
