Season 2

I only started because those who finished season 2 confirmed that both seasons are one story, and they're right. It's really best seen as one 12-episode season rather than two separate 6-episode ones, especially with season 1 ending on a big cliffhanger. Season 2 also has an ending tease, but that comes during the "epilogue" after the main central story wraps up, and is just for seeding interest for the next storyline (with that cameo! Although I don't know how many westerners will recognize that person).

Anyway, the show is good genre fun, with broad but lively characterizations to make it involving beyond the intense action and light politics; I like that they even throw in a few characters with broadly grey shades on both sides of hero/villain lines to make the groups interesting, like the bumbling magistrate). I actually prefer season 2 better, as it feels like a season-long Act II, with rising actions and story turns plenty. And the show has some of the genre's great, creative zombie action scenes. Doona Bae escaping a room full of zombies by lighting a robe on fire, putting it over her, and then sprint out is pure badassery, without breaking her character's type. All the while holding a baby no less!
