I have watched a couple of them because the only video I have found on some interesting theme has been such a reaction video.

But, I’d say that I do feel kind of comfortable “having someone around” when watching the video. I would still prefer the video without the extra commentator saying things aloud that I can see myself, but I bet there are people who really do get something out of the reaction videos. I’d imagine they are very nice things for the most intoverted among us?

Still, they are there mainly for generating revenue for their makers and for youtube, not so much for some actual need…
