I found several of the female characters in A Song of Fire and Ice to be either annoying and/or pathetic. Sansa has essentially been a passive, abused observer, Cate screws everything, and I mean everything, up, and Ceresi... the less said about her the better. Not that I found the non-royal female characters endearing... or some of the male ones, for that matter...
Ahem. For pathetic male characters I'll go with Edward from Twilight and Caine from the Acts of Caine series. Both suffer from the fact that the author wants you to like them, or root for them, and failed (for me). Edward is a creepy 100 year-old virgin who repeats high school for decades at a time and still lives with his parents. I'm not in the targeted demographic for Twilight, but combined with the fact that he's also a creepy stalking mind-reading voyeur, he brings up comparisons to Herbert from Family Guy.
Stover makes Caine out to be a badass anti-hero, and while 'traditional' anti-heroes aren't a favorite archetype, they're not my least favorite. Stover ruins it by making Caine a whiner. The man is a mass-murdering selfish prick who started a civil war in another world for reality-TV ratings, and I'm supposed to care about anything the man bitches about?
