I wouldn't be annoyed over the "weak but attractive females, strong and brawny men" if it wasn't yet another example of nonhuman species attractiveness being inexplicably compatible with human beauty standards. They're aliens for gods' sake. Why do they need to be constrained by the 'muscles and boobs' limitation that every other non-animal-based species appears to be constrained by?
With females being barely-clothed nubile space babes and males being hairy gruff beast-men, even the emphasis on their value on mental qualities feels like just a bandaid on the gaping wound that is the history of 'alien' women being portrayed solely as the idealized fruit of sexual conquest and 'alien' men as ugly brutes unworthy as rivals for female attraction.
Such tropes of pandering to male-centric fanservice and sexual conquest should not be used in any seriousness in the works today, even as a reference to olden days.
If neither sex of the Lashunta were at all humanoid, especially attractive humanoid, I doubt we would even be having this conversation.
