12th Doctor:
The Warriors is 100% a modern adaptation of Anabasis.
My understanding is that Anabasis is pretty grounded in reality as the real, if dramatized, version of what happened.
The Warriors has a fantasy feel to it. The colorful and eclectic gangs, the fairly 2-dimensional characters all around and the "challenges" that they face reminded me a lot of the Odyssey. Basically "morality vignettes" where those who chose to be terrible people get bumped off.
I'm not denying Anabasis, I just think that there is a broader look at greek myths in general as opposed to a direct and pure re-telling of a single story.
