Janeway changed a lot
I've been rewatching the series, but started with seasons 4-7.
Now just started watching season 1 and blimey Janeway was really different at the beginning. A touch fanatical, a very clipped way of speaking and slightly aggressive.
They also made a point of showing her softer/emotional side whenever an opportunity to return home presented itself, or when she decides that the Doctor deserves more respect from the crew.
In later seasons she definitely mellowed and became more nuanced.
She let her hair down in more ways than one.
