For me, at 73 years of age, it's a generational gap and a cultural drift. That half-time entertainment is well within the "culture of TV and entertainment". Try to remember that both Cher and Brittany Spears entire acts revolved around "bad songs, poor singing and choreographed stage shows" to make up for lack of actual talent 20 years ago!. They - these types of acts - have been living off of "the visual" Las Vegas Show model for almost 3 decades now.
Quality TV is very rare. Good luck finding it.
