My god, Season 3 is brilliant so far. Most of my criticism about the earlier seasons is gone. Colonel Tigh is brilliant in his 'terrorist leader' guise and incredibly brutal. The whole suicide bombers and terrorist campaign the humans wage is also very interesting and I am amazed that such a popular US TV series has that story arc centered around it's "heroes".
Anyway, Season 3 has really got me looking forward to watching the next episode, and the next, and the next...etc. I'm very glad I'm watching these on DVD though as I can watch several in one sitting as the cliffhanger endings would probably kill me if I had to wait a whole week before seeing the next episode. Coming into TV series late has its advantages in places :p
