Finally some non-Force Sensitives!
Zeb looks sweet. He's definitely going to be the source of lots of laughs and badass moments. It's nice to see that he's not an outright copy of any previous characters that come to mind.
Sabine is cool, too, actually. Like Zeb, she's mostly her own thing. Pretty original character. Not your standard Boba Fett/Jango Fett clone (puns!) or post-Traviss Mary-Sue badass warrior god Mando, not super serious soldier type, not pacifist New Mandalorian or Death Watch sinister evil. Just a fun, normal character, which reminds us that there's diversity for these people still.
So far, these are the two characters I'm most interested in. I'm glad they've revealed them now, because with all the Jedi talk it's been kinda hurting my hopes for the show. Now I'm definitely back to feeling really good about it.
