Those emotions are controlled. You feel sad because something sad happened, but not to you. This is basic empathy. But it's not the same. And the only reason you feel empathy, typically, is because you can relate. But you wouldn't be able to relate if you had no sadness yourself. Because you never allow bad things to happen in your little metaverse.

How does your mother die in VR? How does your best friend die in a car crash? How do you learn your Grandpa doesn't recognize you anymore? Or to learn you have a terminal illness? How do you get so nervous to meet a person your face feels like it's on fire, work up nerve, get rejected, and go home wanting to die? Those are real feelings entertainment cannot reproduce.

Nothing virtual is real. No movies are real. Not yet, at least.
