BSG Unfinished business

I am back to watching "Battlestar Galactica". I have also watched Korean film "The Host" today and it was so good and absolutely not "just horror", but rather a dark comedy and scarily truthful investigation of society. But more about this later, BSG!! I haven't watched it for about 4 weeks and absolutely despaired that things will ever be good. But amazingly, the creators pulled the rabbit out of the hat and explained it all (at least for me)
