They made Elon play weirdos all night; having him as Wario was perfect. And the twist at the end was nice. Everything in between was, I'll admit, not so great...
But that was the weakest sketch of the night, the rest of the show was actually surprisingly strong! (Well, after the awkward monologue.) I'm not an Elon fan whatsoever, but he won me over with his commitment to his eccentric oddball characters and so I awarded him a B for his overall hosting duties.
(Also helped that they picked such a strong musical guest, Miley made 5 appearances and killed every time.)
