Am I defective?

It's not you.  Remember,  the YouTubers get paid by their views and subscribers.  The bigger "act" they put on, their "over the top" actions so to say, gets "clicks" and "upvotes" -- all which earn them more money.

Some reviewers are truly moved and earnest in their feelings and reactions.  Most are pure horseshiite -- pardon my cynicism in my old age.

Well, I have decided I am not totally defective. Disturbed’s version of Sound Of Silence does give me goose bumps especially when watching the B&W video. While I have always loved the S&G version it took Disturbed to show me the words are angry and should be sung that way.

My wife had a friend who was an opera singer.  She came for a visit & we ask her to sing. She went to the far corner of our living room & cut loose with a voice that brought tears to my eyes. It was unlike anything I've ever experienced.

It certainly is you. Madame Butterfly La Boheme and a number of other operas often move me to tears.

Acting isn't that hard.
