Maybe it's too on the nose, but probably, the signature style for Maggie should have reflected her military background in some way: a camouflage pattern in pants or jacket, or always some hint of militaristic green.
I see why they didn’t. People really didn’t buy the military aspects of Maggie. On top of that, no one was that interested in the added military background from Rembrandt. I’m also going to go out on limb and say the season 4 writers didn’t see much action.
MSZ said in some interview (perhaps the one with Torme?) that Kari wasn’t the best actor, but he did study her earlier work and realized that she did have strengths they could lean into. He thought the best bet at turning the character around was to follow that bliss. I’m sure they also asked for her input as well with this revamp and it’s why she ended up having carte blanche on her own hair. I was never bothered by it. Hair/location/budgetary changes are what define the different eras of “Sliders” for me anyways.
Kari mentioned that she was going through a period of self-discovery during seasons 4 and 5. I would’ve loved if they used that as some jump off point for character development. Sliding from place to place and seeing all sorts of other versions of yourself could definitely make one question their own identity/sanity. What if season 4 opened with Quinn having to deal with sliding with an unstable partner in Maggie? What if her mental instability was some kind of a shield that block the Kromagg mind interference.
Now I’m just re-writing season 4 27 (jesus, 27?) years after the fact. Carry on.
