Full disclosure: I have no idea who this entertainer is, although I have heard he's popular with the young folk...Some of the young folk, anyway. Each generation has its own music, and each generation thinks their music is the best. And this generation will be told by many of the next generation that their music is old and stale - It just hasn't happened yet.
That said, this particular halftime show didn't repulse me, but it didn't grab me either. From what I have heard by those who know more than I do in this genre, this particular halftime is not expected to have a long shelf-life, and is destined to be quickly forgotten. IOW, Meh. Time will tell.
Considering this was not a particularly compelling Super Bowl, perhaps that is appropriate.
Personally, I prefer Marvin Gaye.
