Then Japanese started to add those small reaction screens in the upper corners of the TV-competitions. Now it has taken over the world. Shows like MythBusters turned into collection to extended reaction shots to stuff that happens repeated over and over. You can see SpaceX having employees arranged to react and cheer and film crews filming the reactions half of the time.
We are spoon-fed with cues on how to react and reaction pics and interviews of people telling how amazing it and hyping it up has taken over.
Some people can find it draining, but I think there is good reasons why it's done. Competition for attention is fierce.
I think this is basically the same thing as a much older practice -- would you enjoy major holidays as much if people weren't so festive about them?
A sitcom with a laugh track may be less cinematically pure than the same sitcom with austere silence in the background, but watching a sitcom as a bonding activity works better with a laugh track.
So all things considered, it makes perfect sense to me for SpaceX to basically declare that certain occasions are SpaceX holidays and people should show a little more joy than usual.
Cool how two people can get completely opposite vibes from a picture :)
