In part, correct. It's also about the people OBSERVING those inside the apartment. Without the observers, the 'insiders' don't exist. As an observer for 10+ years, their social awareness/interaction with others has not developed as it should.
Their reliance on an income...a profession they can have for the next 25 years...not going to happen. I assume she wants a baby (forget about raising a kid on cam). Him fiddling fixing inexpensive electronics - someone tell him we live in a disposable society. We don't fix a TV, cell phone, tablet. We throw them out and buy another. There's so much wrong with these two being on cam after 10+ years.
Pleasing to the eyes, absolutely. Go just a little beyond the surface, a very rough road is ahead once they go off cam.
