This is the best show on TV at the moment so if you are not watching it I suggest you give it a try.It has everything you could want in a show of our liking.
It's part Doctor Who/Game of Thrones with much better writing and characterization than both imo.
Unfortunately season 3 will be the last due to Starz canceling it in favor of more Black Sails which is an inferior product.
Can't wait
