First, cast Chakotay with a human actor and not a wood one. Then mane his Native American stuff real and not stereotype.
I disagree. I like Chakotay and when you change actors you change how the chatacter is presented. This is why recasts often struggle to find footing. I would not recast any of the actors. You risk messing with chemistry and potentially creating a horrible work environment. Like Beltran or not, he got along well with his castmates. That is gold if you want people to stick around for 7 years.
