I polity disagree with the above sentiments.
Fact of the matter is reviews were a big draw for both youtube and the website. While you might be only tuning in for the personalities instead of reviews, a solid chunk of traffic was made up of people who did the exact opposite. GTs reviews were in many ways one of bedrocks of the site. Going forward that might change, but it's my hope that it doesn't.
True, a lot of GT's reviews got like half a million views upwards, definitely their highest performing output.
