It's been a long while since Battlestar Galactica had an episode focused on the action, with drama set aside and the guns drawn out.
The episode gives a 40-minutes long adrenaline rush, showing a massive uprising aboard the flasghip of the fleet. Nearly every character ever seen (And still alive) in the series picks his side, even people that had a one-time memorable scene in an earlier season.
It's been a while since the audience's favourites, especialy Kara and Lee, took part in a real fight, and it's hell of a ride to see them back together in the action.
Adama's ignorance of the uprising is somewhat shocking, in a good way. He isn't the perfect keen-eyed leader as before. He's broken and tired, and lets himself to be fooled in a heartbreaking way. Having Adama threat of retribution is one of the scariest things in the episode. EJO is an amazing actor on every turn.
