To put it into perspective: Cinemas in Japan are chill, it’s not like American or “Western” cinemas where people shout aloud at hyped scenes or laugh so loud where you can’t even hear what the dialog is or talk amongst themselves causing distractions (or yet, using their phone at max brightness that becomes distracting towards other viewers).
Instead: it’s more on immersing to a movie at your own desire, everyone for the most part is dead silent because they know that they are inside a cinema as courtesy is considered, while I’ve heard that is starting or has already started to decline in the US (& Western nations) since the experience of being in a theater isn’t the same as it used to be.
Despite what a lot of tiktoks show for shit like the Minecraft movie, I have never experienced that in real life except when going to see Rocky Horror Picture Show, where audience participation is part of the fun. People are generally quiet unless something funny happens that makes most of the audience laugh.
