Personally, I'm not a fan of reaction videos. Maybe it's just me, but I don't find them to be very entertaining at all, and only sometimes can be marginally informative. In fact, more often than not, I've found them to be more indicative of the creator's lack of inspiration or originality when it comes to content creation in general.
To me, they are just a cheap method for somebody to put "something" on their channel, just to have something "new" on it, because they can't think of anything else to do at the moment, or aren't close to completing better content (reaction content is one of the easiest things to do.)
