The first time I read Treasure Island was immediately after watching Black Sails for the first time, and let me tell you, that was a fun experience. 

Reading it again now (for a pirate literature class) it was also fun (not as fun as after Black Sails when all the characters from the show were still fresh in my mind, but still very fun). The characters are fun, the book is adventurous, you're probably going to have a good time.
