Those things and a movie theater aren't similar in any way besides being around people
Concerts & festivals you pay to be part of live vibrations coming from the performer, band, and yeah other people.
Nobody not a serial killer is trying to catch the vibes of people in a dark movie theater my guy. And people have complained about loud ass people, kids not shutting the fukk up, somebody eating a 30 minute old pulled pork sandwich they snuck in stinking up aisles etc since movie theaters existed.
Two completely different social gatherings. One is for bonding, the other you had no choice until now.
