^ I think that's more a result of bad writing than bad acting choices. The character of Janeway was written so inconsistently that I could see how it would be difficult for Mulgrew to realistically portray the character (one episode she's depressed about being in the DQ the next she's saying she never questioned that decision)
You can't blame everything on bad writing.
If someones body language is off that's either the fault of bad acting or bad directing. For example: Mulgrew standing nearly nose to nose with someone while talking during the first 2 seasons has nothing to do with writing. That's bad improper directing and acting. That works in daytime soap operas, not in night time drama. As Voyager continues, you can see Mulgrew stops doing this. The scripts didn't change, the direction on how to play the scenes did.
Agree with you exodus - the old "blame it on bad writing" cliche!
Those "nose to nose" moments early on were "scary" - still makes me laugh when I see them. The other thing that struck me as really unnatural - and in later series, was the hand on the hip. It always reminds me of a pregnant woman with backache. I'd love to know who made the decision to persist with that stance.
