I wonder if some of the nagging feelings of character anonymity among the Astro-Sioux were due to unpronounceable names, or at least names that don't easily resonate with moviegoers not versed in the Astro-Sioux language. Han Solo and Chewbacca still have recognizable counterparts in the English language. Hence, their character names are easier to remember. Hah-eh-eee-ay-nah? Not so much. I can't recall a single Astro-Sioux or alien critter name from Pandora, and I saw the movie less than 48 hours ago. It could be encroaching senility. But maybe not.
