Interesting reactions. I generally like The Weeknd, been a fan of his since about 2012 when he dropped his mixtapes without revealing his identity. Surprisingly, I agree that his charisma is about as high now as it was then (with literally no identity) But his music hits some notes that there aren't much of in today's music. He can do the R&B thing, heavy on the synth-beats and loops (which I'd assume catches some EDM crowd), and then recently added unashamed pop music to his repertoire to catch the youngs. It's probably better than he doesn't have much charisma/personality though, he's literally made a career singing about cocaine, partying, strippers, cheating on girlfriends, and doing cocaine at parties with the strippers that he's cheating on his girlfriends with.
The performance was ok. I can't stand the medleys though, one verse from each song that I can't imagine would make anybody a fan. You can hardly get a vibe from any of them. Otherwise I've seen reactions that he needed a stage, that the stage-less design was cool since he used the field, and now that he didn't use enough of the field. Can't please everyone.
