I definitely dont agree that a new Woodstock should be old musicians, it should cater to the popular music of the day, same as it did originally! But theyve done a nice job bridging the many genres and much broader scope of music over the past 50 years, while still including lots of the classics too.
That said, it is shit and all festivals now are huge easy corporate money grabs. But in essence truly they suck, because people suck. People are so boring and basic that the only way many folks know how to get away from their daily work eat tv routines is a cruise ship or a premade festival experience. There's a crazy giant market, people eat it up. Pay hundreds to go and pay hundreds more for $15 beers and hotdogs
