Reaction videos have been for many years always very profitable. I mean, you can easily find creators/channels that have millions of views and they just film themselves reacting to a video. As a creator, you can incorporate a bit of that into your content and you'll likely see people engaging more. I personally never understood what's the appeal of watching somebody watch something instead of me watching that directly. I think it is something that goes in the direction of a para-social relationship, but I'm no expert.

Edit: I think I might be thinking about a different kind of reaction videos mind. Sharing an example of what you were referring to?

It is gross, but watch a child watch the video. They look to the talking head to interpret what is happening and to tell them how to react.
