Spartacus is a historical depiction of ancient Rome's society and culture.The intensity of the sensuality, brutality and language is to suggest an authentic representation of that period.
First, an authentic depiction of Rome's society and culture? So, both Rome and Thrace were inhabited by gorgeous British underwear models?
Second, authentic brutality is not attempting to emulate "300" mkay? Slow motion fight scenes, lots and lots of freezing time in fight scenes, and computer generated blood that splashes the camera are NOT how it went down, I'm guessing (I wasn't there, to be fair).
Xena: Warrior Princess is a more gritty, realistic portrayal of ancient warfare than this show.
And really, that's fine. The only reason I felt the need to call this out was that hilarious disclaimer at the beginning, which might have been the best thing about the pilot.
