This show isn't deep, it doesn't dig into Rome and the reality behind the Republic and Empire. However, the show is capable of delivering the guilty pleasures of blood, violence, slo-mo insanity, nudity, nipples, Lucy Lawless naked... while also delivering several interesting insights into Rome.
The show does start out slow and simple - Blood blood blood sex blood sex blood. But around the 6th episode, the pace picks up and you get a little bit deeper. This is also about the time the HSQ picks up - Surprising deaths, manipulations, things you honestly wouldn't expect to happen occur and literally make you go Holy Crap!
Good show - Not deep, just fun.
