I watched the pilot episode and wasn't that impressed and a long time after I watched the second episode and enjoyed it. I always planned to watch more but just never did.
It most def gets better as you watch. So far it dosen't seem to be as "zomg LOST-style" mystery as much as BSG was, but its still really worth watching.
I am hoping it will get better. For myself, it seems to be going kind of slow. I think they are mostly building characters and plots at the moment, so the main action will be happening in the up coming episodes.
I didn't get a thrill from he first episode, but will catch it up on Hulu.
In other breaking news.. they just got a green-light to do a new Battlestar series on young Bill Adama and the first cylon war. Should be exciting stuff.
