There are three BIG problems with reviews these days.
1. Sites don't seem to have a standard for their reviewers to follow. Sure, there will always be differences in opinion and tastes, but some things should be standard. One being glitches. Where one reviewer will completely give a pass or just take .5 off for a game having glitches (even some game breaking ones), just cause they had fun, another will take off a few points. It should be the latter if the glitches are bad enough, but some companies (especially Bethesda) get the former treatment.
2. The grading scale seems to have been changed last gen, with some sites seemingly trying to get back to the older scale this gen, but without explaining it to their readers. The old, and correct, scale has 5 as an average. The one from last gen had 7 average, like in school. The reason this doesn't work is you have only 3 good ratings, 1 average, and 7(!) bad ratings. That makes every thing that's just an above average game an 8+, inflating ratings for games that don't deserve to be rated that high. Where 6s and 7s should be decent games that people should definitely check out if they like the genre/franchise/concept, now gamers see games with those scores as complete shit.
3. And the worst thing wrong is reviewers who use their ratings to either make some point that's only important to them, not really looking at the game objectively, or to just get clicks for ad revenue. These two are pretty self explanatory, so I won't go into them.
Edit: Just watched the vid. Seems like we think the same thing.
