First, Ginnifer Goodwin. As Snow White. A crazy-awesome-and-kills-trolls Snow White. Come on!
Second, Jennifer Morrison as Emma, Snow White's daughter. Time stopped for Snow but not Emma, so it makes sense. These two are the Jensen Ackles/Jared Padalecki of ABC. It's almost laughable how beautiful these two people are.
Third, Red Riding Hood/Ruby. My favorite non-main character. Her story is freaking awesome. For real.
Fourth, Robert Carlyle as Rumpelstiltskin/Mr. Gold. Characters who are on their own side are always among the most interesting.
A couple episodes ago, Emma and Snow/Mary-Margaret were walking to a beanstalk with three others to steal a magic compass from a giant to try to get back to our world (simple reason - Emma wants to get back to her son who she adopted out 10 years ago [Henry, who was adopted by Regina/Evil Queen] and her newfound father [Prince Charming/David] while Snow White wants to get back to her recently remembered husband [Charming/David] and newfound grandson [Henry]. Just watch it). The three others traveling with them were Aurora, Mulan (!!!), and Captain Hook. Besides the later seasons of Buffy, how often do you see a group make-up like that? Usually you get the smurfette principle and see one woman with four men.
Like every feminist, I like to see gender equality in general. (Oh, and just so you know, if you think both men and women deserve to be treated as human beings, you're a feminist). Women may get more screen time in this particular show, but it's so incredibly rare that this happens in television and film. It just keeps enthralling me when I watch a scene like the one above. It's just so cool!
If what I've written thus far hasn't convinced you to watch it yet, this last thing will.
Red Riding Hood is a werewolf.
