I didn't plan to spend all of my sick day writing about this. But in the face of some of the comments so far and an article that was just brought to my attention which mentions the tendency of the female characters to be portrayed as victims this season as one of the ten biggest things the show needs to fix.
Of course this isn't the first time I've reported on this. And there's even a whole article on it at HEROESWiki.
I think it is a lot more obvious this Season though. I mean, think about it...
Claire - literally mind-raped by Sylar. Abandoned emotionally by Noah and Peter.
Niki - one of the two main female characters when the show first started - confirmed dead. Killed while trying to save Monica.
Monica - good bloody question
Tracy - started out as a powerful and confident "ice queen" who cracks (no pun intended) after accidentally killing someone, finding out she's the victim of gene-splicing and has sisters she never knew about. Tries to commit suicide and becomes the love interest of one of the main male heroes within minutes. Looks to be a trophy wife/First Lady in The Future.
Daphne - presently a super-fast thief who manages to regularly outrun Hiro physically and mentally. Is apparently destined, sometime in the next four years, to go straight, become a Company Agent, have a baby and become Matt Parkman's love interest in The Future.
Maya - has always been an annoying victim of the male characters' manipulation. This season, suddenly changed into (alternatively) a nag who badgers Mohinder and... I'm detecting a trend - Mohinder's love interest/love slave if my theory about him becoming a cockroach with pheromone powers is accurate.
