I just think the series would stood a chance of improving if Janeway left. Harry could have actually done something if Janeway left, for one thing, he would half to deal with the Captain being a maquis officer, that would at least given the character a better chance to grow.
That would've worked if the show had ever paid any attention to Chakotay being a Maquis. But that stopped having any importance as soon as season 1. I don't know what the point was of having a Maquis first officer, when he acted like just another Starfleet officer and never stood up to Janeway. In
Equinox, when he stands up to her for a moment, while she is acting insane and really crossing the line, but then he caves in, and in the end says that it would have been "crossing the line" if he had mutineed against her. Hello! This guy was a
Maquis, he had been an outlaw because he stood up and fought for what he thought was right!
Which is why Chakotay could have left as well... he had very little to do on the show, especially after Seska was gone.
