MINISERIES PREMIERE: This is more warning than recommendation. This Michael Bay TV production has all the action set pieces and random violence and nudity you’ve come to expect from his movies – with characters just as thin, and actors who, for the most part, look a lot better than they act. In the case of Black Sails, this is a shame, because it’s borrowing characters from another, much better pirate story. Black Sails is a prequel to Robert Louis Stevenson’s Treasure Island, with a younger version of (Long) John Silver, played by Luke Arnold, at its center. This drama looks good, and its genre and setting certainly is different – but a swashbuckler, in this day and age, needs good writing to stay afloat, not just boats, beatings, and breasts.
