Depends on the person reacting and what they are reacting to. If it's "watch your crush react to your singing in the shower" I'm sure that'd be entertaining. (as long as it's natural reactions and not acting for the camera)
But most of these reaction vids are pretty pointless and not worth a few seconds, but that applies to all forms of entertainment whether it be sports, tv etc.
