Yeah, don't get me wrong; Seven wasn't a bad character at all. And I completely agree that Chakotay was a bit under-defined as a character. But I simply attribute that to the writers themselves not really being interested in him enough to define him better or use him more. Maybe that was because of Beltran's acting... I love theatre and such, but I can't say I'm all that good at telling good acting from bad acting... If I can believe their feelings, that's good enough for me and I always thought Beltran shows a lot of emotion in his eyes. 😅
