Which EDM sets have you attended that you hated the most and why?

Personally, I haven't been to any sets that I hated, but I have two examples that do in some way.

1. Boris Way at the Olympia in Paris, France: he was opening for Alan Walker. His set was very good, but I found his set less interesting than Alan Walker's. The sound quality was poor, and he only played for 30 minutes.
2. Maeva Carter at Vertical Music Experince, Valfréjus, Modane, France: Her set was awesome but the crowd ruined it. There were a lot of people drinking too much alcohol and smoking cannabis, and even people mixing alcohol and other drugs. We ran away halfway through the set because of this and also to leave before everyone else because there is only one road to access Valfréjus. Some will say "yes but it's common at EDM festivals." This may be true for the US, but not in France. The other EDM events I've been to (which were only on French territory by the way) didn't have this problem as much (I haven't been to the nightclubs so I can't say if it's common here or not). Also, I don't have a problem if people consume alcohol in moderation, i'm just against alcohol abuse.

And you, Which EDM sets have you attended that you hated the most and why?
