I'm gonna disagree with the other guy, it reminded me a lot of black sails. Deadwood definitely has better writing but there's a lot of similarity in the characters imo. Maybe it's just the time period and accents

I watched both for the first time recently and I agree with you. Think that's partially due to Rome having some dodgy cgi and going for a more distant time period, I imagine most of the props used in Deadwood were readily available for instance
