People tend to not like this one, but usually for the wrong reasons. The 4.0 stuff is Fine honestly (I have some Opinions on how it handled the Au'ra), one of the best depictions of a conquered people suffering from colonialism out there. It's when you start getting into the 4.x story that it comes at you with some Very Questionable Takes, like "giving refugees financial support is bad and will make them lazy, you gotta give 'em Jobs", and "Selling your daughter to Vaguely Implied Sexual Slavery is fine, actually."
