Blackbeard: Terror at Sea

I am currently writing a fictional novel on the life of Edward Teach and in doing so I have been researching this topic for little over a year. I thought I would watch this to get more in sight into the character of Blackbeard. However the research conducted into the period and into Edward Teach himself is very poor, almost as if they have only looked into one source for their research. I am only part way in to watching but am already slightly disappointed on the lack of structure and diffinative lack of depth. It feels more like a taster of a portion of pirate lifestyle than a factual telling of the life of Edward teach, or at least what we know of it. Seeing as this is supposed to be a factual representation and not fiction, very, very bad research.
