I would have loved to have seen a flash back episode of her fall and rise. Start with her assignment to Chakotay because she was the best of the best or she was being punished, her seduction and inclusion of Chuckles, spotting Tuvok as a spy too and deciding about whether to kill him? Her own conversation with the Caretaker? Left behind stragglers from Gul Mossets crew, bodies even? the Cloaked ship from the Voyager Conspiracy, why she gave up on Janeway, attempted and vetoed relationships with other space empires in the DQ, you don't think the kazon, despite being so easy to manipulate, since a loyal dog is better than a clever dog, was her first choice? Then her inception and eventual assimilation of the kazon followed by her mad quest to strip Voyager down for spare parts and lift the Kazon up by their boot straps completed by her death from a slightly skewed perspective revealing something we didn't notice the first time around like love or hate.
But no, they'd rather have another story about a space vagina puking time while one of the crew relearns a valuable ethical lesson they already learnt three weeks ago last time it was their turn through the wringer and their parents deserve a good slapping for never teaching them in the first place.
