The thing that really gets me about Elektra is that I should like her. I normally enjoy morally ambiguous anti-heroines and hero/villain pairings (Batman/Catwoman, Buffy/Spike and Buffy/Faith, Clark/Lex, etc.). In theory, Elektra's just the kind of character I love, and her relationship with Daredevil is the sort of stuff I eat up like the melodrama-whore I am in other fandoms... but in practice, she's so frequently written in a way I find annoying that I can't bring myself to like her.

Also, Jennifer Gardner played her in the movie.
