For me, the first episode was good enough for me to check out the second. I like that the characters are a mix of historical figures and Treasure Island characters. I love Vikings on the history channel, and this show sort of had a similar vibe, though I still prefer Vikings.
Edit : Blackbeard
I liked it, wasn't expecting much but the story, especially Captain Flint's scheme, is very intriguing. Will definitely be following this series.
