The original Spartacus show wasn’t great. I admit that I almost quit watching after the first few episodes. But it improved a lot towards the end of the season. It seemed like they aimed very low to get dumb people to watch then they hired some real writers and transformed the show into something engaging.
The actor who played Spartacus last year isn’t coming back to the show, they delayed his return by making this prequel series. They’ll recast him next year. I’m kinda hoping they bring one of these characters into the second season. Maybe it’s not possible, gladiators tend to have short life spans.
Or try EW.
