To get it out of the way: If you can't stand a naked breast; skip this one. I know how some people are very sensitive to naked skin, but I guess a chopped off head is OK? (Yes, I'm kicking your way you "Oh, that's Janet Jacksons covered up breast on live TV. I have to call the TV network"-people).
Each episode added a new layer as I see it. The characters grow in dept, and the conspiracies grow ever more entangling. I always wanted to see more after the second episode. The show exploded! For a show like this to even work the producers had to make a choice between kiddy-TV and adult TV. They chose the latter and hit the damn spot. Spartacus Blood and sand is one of the few shows that is just for us "big kids". I don't care if people are naked or headless on TV, as long as it suits the show. In this case it had not worked without it. Praise the gods that someone had the guts to think past the double morals of todays television and just press on! Rome was no flower-covered heaven on earth.
The acting can seem stale at first, but each actor grows in their role as the show progresses. A few of them impressed me, as I had deemed them to be c-graded actors a long time ago (Xena, anyone?). Some of the stars of this show seem to have found a show that suited them as much as they suited the roles they had to fill.
To avoid spoilers I will not say much about the story. What I can say is: The story evolves at the same rate as the actors/characters. Nearing the end you will beg for more! It's hard even to catch your breath after what I have just seen: The last episode offers the greatest form of chatarsis I have ever witnessed/felt in a TV show.
I will root for Spartacus in season 2 (and 3, and 4).
Sorry about the spelling errors and such.
