Man. 90% of the characters are unlikable assholes and bitches. The only redeeming ones I've found so far are Chelsey, May, Elsa, and maybe Erin and Bianca (but they have such a small role). I get it, Frank is a criminal, but there have been plenty of criminal protagonists that have redeeming qualities about themselves. Sometimes, he seems ok, but then he'll do something that just makes me wish he was the antagonist, and there was another protagonist that will eventually give him his just desserts.
Eva did a complete 180. She was just like any other hot girl that fools around with the MC during her introduction. After that, she became a conniving bitch preying on the innocence of Kate, while trying to sabotage Frank. Granted, I don't like Frank either, but her attitude shift seemed so sudden and contrived. Could have at least tried building up her shift in attitude instead of just changing her personality as quickly as her appearance changed.
Marty is a scumbag. Enough said. And every other character isn't important enough to delve into, but long story short, they're awful, too.
