Beltran is an actor, and would have wanted his character to be well developed. the fact is it was not
we never knew what tribe he came from. we never even knew who his mom was, or if she was still alive. And his native American heritage was one of the defining aspects of the character.
Chakotay's poor characterisation was one reason IMO why Voyager only was a good
show, and not a great
show like TNG and DS9.
that's a bit harsh, the great distance made visits by mom and dad as plot device difficult. it never crossed my mind to criticize ds9 and tng for not introducing me to o'brien's, jadzia's, and riker's moms. they had more serious issues. ds9 for example, a first officer constantly on the edge of a nervous breakdown. i liked the nice and quiet 1th of voyager a lot better.
