11. James Franco and Anne Hathaway (2011). Always beware of courting the "young," particularly two young people who are basically 50-year-olds in grownup clothing. Franco, stripped of all self-referential schtick, turned into an empty suit with nowhere to hide, and Hathaway's desperate attempts to pep up the room made you want to dive under a chair. Whenever someone says, "Hey, try hosting the Oscars, it'll be fun, whaddya got to lose?" one need simply point to these two.
10. Seth McFarlane (2013). McFarlane had a few jokes that landed and was certainly trying—which is more than you can say for those two above—and I've always thought the mean-spiritedness of the show was somewhat overstated by those who reflexively dislike McFarlane's work (this includes me). This was still a shitshow, if just because McFarlane, whatever you think of his wit, just isn't that natural of a performer. The four hours McFarlane hosted the show was the most time he'd ever spent alone in front of an audience like that, and it showed. It's still bizarre they ever asked him.
