Yeah this guy's reactions are weird. I think he means well, but I truly don't think his mind is made for metal. Some people just have that metal "spark" so to speak, and it doesn't seem like he has it. I highly doubt that he will ever listen to Six Degrees ever again, even though he said it was "the greatest album" he has ever heard.
A great reaction channel is Lost in Vegas...two guys who are into rap and hip hop and finally gave metal a chance. They really break down, dissect the music, and give their thoughts on the song as a whole. They're great. When they hate a song, they say so, but their thoughts are very insightful, they put a lot of effort into their reaction videos.
