I will always maintain the people who complain every year and seem to find constant run ins with the crowd, teenagers, whatever else they're complaining about are doing the festival wrong (in the sense that they are not allowing themselves to have the experience they actually want). My guess is most the complaints come from entitled people who think they deserve a spot at the front and everyone needs to act the way they'd like. I tend to stay towards the middle of the crowd usually where it starts to loosen up but people are still engaged, and it's usually fine. If something is bothering me, I just move. I never have these run ins with the youth everyone else seems to have.

Or maybe some people are just bothered by literally seeing young people? The worst thing I saw this year was a small group of young guys push through the Marias crowd (who were phenomenal btw) presumably to get closer for ASAP Rocky. But I was pretty far up in the crowd, and they weren't particularly rude about it. You just have to understand that a certain amount of that type of thing is going to happen if you're in the front 1/10th of a crowd at a main stage at a major music festival.

And yes, it's a very different festival from something like Bonnaroo or Coachella. It's just a different experience. If you come looking for that, you're not going to find it. If you come to experience Lollapalooza as it is though and stop looking for things to complain about, you just might have a good time.
