Nothing unpopular about #9. Cliff was an outrageously solid recurring character. I would've loved to know more about his and Keith's relationship when Keith was sheriff and their relationship would have naturally been more adversarial.
11 was a shocker for me. One Angry Veronica is one of my favorite episodes. When I do a rewatch, it's one I always look forward to. What problems do people have with it? Is it too awesome?
