> It's not much different from watching a movie with a friend at your own place

not to sound rude, but that's a bit of a stretch.

It is much different.

Maybe not better overall for some people, but very much different it is.

> VR gives the activity sense of presence which is hard to describe

Not really hard, it's similar to proprioception

Difference is proprioception enables you to feel limbs that are actually there, which is not as good as tricking your brain to feel something that it's not there.
