I'm torn, part of me would love a S2 simply because I thought it was such a well done, thought provoking show and there are many cliffhangers to be put to bed. However the other part feels a second season is unnecessary a lot of the cliffhangers we can just use our own minds to answer the questions or maybe they should be left open ended. Hannah's part of the story is essentially done, the title of the show specifically refers to 13 reasons why she killed herself we know them now, any other story would be irrelevant to that.
