Why the hateration for Mika? (Ninja Assassin)

Okay, so I saw Ninja Assassin for my birthday, and I loved it. Not a deep movie by any means, but one that more than fulfills the promise of its title: it's about Raizo, a NINJA who is also an ASSASSIN! And he has a DARK PAST! And he fights a shadowy CLAN of EVIL NINJA ASSASSINS! He ANGSTS! He is joined by Mika, a BEAUTIFUL Europol agent who is also fighting the EVIL NINJA CLAN! Together, they kick ass! And have UST!

On fandomsecrets, there's a secret lamenting how there's no fandom to celebrate how awesomely shippable Raizo/Mika are. Fangirl reaction: lots of Raizo/Mika shippers and several haters who declare that, among other things, Mika is "annoying" and a "useless bitch".
