13 People she's going to torture
It was like an evil version of PS I Love You- it was hard to feel sympathy for Hannah when instead of taking any responsibility for her own actions, she was assigning blame to 13 people with her little tapes of hate and trying to screw up their lives from beyond the grave as a result. Bryce was legit awful, but things like the doofus Asian guy throwing away her note was pushing it. It would have somehow been better if they had been 13 people who teamed up to conspire to kill her, Murder on the Orient Express Style... which is what it kind of became, when they had secret supervillain meet-ups to decide what to dow with Clay. "Where are the tapes?? What will he do with the tapes???" It just became this silly Hannah Revenge Squad like they plotted her downfall.
And Clay should not have been included- I don't know why he felt guilt at all for his actions. Why were they telling him things like "Did YOU do it? Have you heard your tape yet? You killed her!" It just didn't hold up to snuff when we finally here what his big "misdeed" was. I would have preferred it if they had had him actually do something hurtful and regret it, but I don't understand why she crapped all over him and then never told him how she felt when she knew he cared for her. She had him and her parents, which is more than some people have.
