People love moaning on social media, and moaning about Glastonbury is now as much of a tradition as the festival itself - especially amongst oldies who haven't come to terms with it not being 1984 or 1994 any more, the good old days when you could watch Proper Bands like Doctor & the Medics or the Thompson Twins.
With 2000 acts across 100 stages it's easy to find a few performers you don't like to point at and say
see! its rubbish now!! But it's also easy for anyone whose mind is even slightly open to find something they do like. With that much happening from so many different musical styles (or if you're there you can just watch films, or make pottery, or do hippie shit, or never leave the campsite and just stumble around chatting to people all weekend) the festival can be whatever you make of it.
As a TV watcher my favourites were Confidence Man, Nia Archives, Justice, Alogte Oho & his Sounds of Joy and Sugarbabes but I'm sure everyone will have different things they did or didn't like
