Some guys listen to an entire song with no facial or body expression which makes me wonder why they called it a "reaction" video when there's no reaction to what they hear/see
Some guys talk too long about things not related to the video (their problems, politics, dad, girlfriend, and so on)
Instead of making comments on the song, they try to figure out what the song is about when there's info on the Internet
Some guys focus on insignificant elements in a song section missing the real gems in that song section
Some guys don't bother to find the version with the best quality available (sound quality and video quality)
Not truly understanding the song context and just sitting there grinning and smiling, not listening to the lyrics while rocking to the beat of the song, and the song is actually sad or reflective.
