^Me too. It'd be a much better film, imo, if part of the moral conflict had involved the crew struggling with the fact that their duty is to help the Ba'ku, while also realising that they are not noble innocents, but a selfish, arrogant, privileged colony who, through pure luck, are squatting on an unparalleled medical resource and neither sharing it nor using their own protracted lifespans to do a single thing to help anyone else.
They're fighting on behalf of a people who, were the positions reversed, probably wouldn't lift a finger. Acknowledging that would make for more interesting watching, I reckon.
