Having been rescued from the slums of Fashion City, Nikita now wears only the most hip sportswear and sunglasses. Ditto for Michael, though his wardrobe usually consists of black or smoky-black suits. The most incongruous part of this fashion-plate cast is Nikita's hair. In one episode, after obviously having some trouble with her bangs, she wears them sprayed straight up from her forehead. In other episodes her hair is limp and scraggly.
Sets are often minimalistic and dark.
Lately, in the second season, we have been seeing more interesting set designs. For instance, in one terrorist's liar, we see mysterious tanks stuffed with naked bald people. The reason for or meaning behind these tanks is apparently irrelevant or beyond the creative abilities of the writers, since they are never explained. Speaking of the writing, I would have to say it is best to ignore it. The show often follows the Rodenberry Formula to Deal with Extras, which is to kill them.
