I have never seen the original show, though I intend to, only the new version, first two seasons and started the third, didn't go further because of breaking up with the guy I was watching it with, though am DYING TO START TO WATCH IT with my Master again!!!!!!!!!
A friend mentioned it to me, saying I will love it as hell because it is FULL of psychology!!! I am not a giant space sci-fi fan (prefer the other sort of sci-fi way more, about strange future and stuff like that), but when I started to watch it, OH HOLY FAKKU, it has blown me away!!!!!!!!
I have watched quite a few other shows since then, so am not sure if I will still say that it is the VERY BEST SHOW EVER!!! Though I guess I will...
It is AMAZING how they go deep into all the different moral and mental aspects of life, and how excellently they give the examples of a billion things about human nature!!! I must say that I could hardly decide if I had to choose if Star Wars or BSG is better! Because they are both MINDBLOWINGLY FANTASTIC, BEST SCI-FI STUFF EVER!!!!!!
