>How important is the first season?
Harlock started off more political and disturbing, essentially a romantic far right rebel. Eventually they tuned it down to Robin Hood in space, and even when they tried a darker take, the conflict was moved internally (a morally ambiguous antihero).
The original series could never be remade nowadays, and the adaptation would scandalize SJWs. Harlock wages a solitary war against an aggressive matriarchy, who infiltrates the passive and indolent society of Earth. He's a stoic man of few words, often shown just sitting alone, who leads by charisma. And when they introduce a young self-insert for the viewer, he's a madman consumed by revenge who's baptism of fire is shooting down the flag of the nation.
