I haven't seen Spartacus specifically, but most shows and movies that are hyped as "gritty," "dark," "edgy," "mature" et cetera are geared toward adolescents who want to feel like tough guys. Perhaps Spartacus is an exception.
From DeKnight's record on Buffy, Angel
, and Dollhouse
, I'd say there's more substance to his work than that.
You haven't heard of Space Command? It's Marc Scott Zicree's current project, which had a hugely successful Kickstarter campaign. The first movie should be out next year. The official site is here. This looks like something we both will love.
Oh, that. Yeah, I have heard about that, but I didn't associate it with a discussion about upcoming TV shows since it's a movie or an online thing or whatever.
