I am familiar with 8 out of the 10 storylines. I think 1, 2, 6, 7, 8 and 9 are the worst. Too surprised the Rogue and Magneto affair from AOA did not make the list. I find it more inappropriate than Scott, Jean and Emma who were all adults. Rogue was a barely a teenager in AOA. Because of Game of Thrones I don't vomit that much anymore with incest stories, although I still voted Pietro/Wanda as the worst STORY on the list.
