May be I am in minority but I would hate to be alone in entire theater. I enjoy some vibe and people around

There are times I would agree with you, and times I wouldn't.

If the theater is full of people talking during the movie or lighting the place up while they’re on their phone (in either case ignoring the movie), then I’d rather be alone.

It seems like more times than not, this is the case.

In a previous life, I would go to a lot of art movies, often matinees or monday or etc. Sometimes there was one guy who was working the box-office, the snackbar, and the projection. I was glad he had a job.

Are you American? US cinema culture seems very different to the UK (the only other place I’ve been). In the US it seems much more the norm to react to the film, in the UK generally folks sit in silence.

Yes this is what people get wrong about "home theater". Its not just the tech, its the experience of watching something with others, amplifying the emotions.
