I'll admit a horrible guilty pleasure: I like watching reaction videos. One topic in particular is the LotR trilogy. People much younger and seemingly right in the strike for the apparently miniscule zoomer attention span can nonetheless pay pretty good attention and enjoy the entirety of the trilogy without any real issues.
