Oh no, I'm talking in general.
Then you're taking the grievances of gamers and summing them up to "occasional slightly sub-par gameplay videos"?
In that case, no, that's not the whole story. I think I've explained it before. It's a clear lack of passion that journalists, as a whole, have for video games. Playing poorly is a demonstration of how little they care. Playing poorly is not the root issue, it is is just one piece of evidence that the root issue exists.
so him being bad at it doesn't really effect his preview article.
Well, ACKHUALLY, he missed out on a large chunk of the game because he couldn't progress. His opinion was limited to what he was able to experience in that short amount of time. For example, he didn't even get to experience the bosses, which are arguably the most popular feature of the game.
Even though it was a preview, he could have
previewed more, if he were competent.
So yes, his preview was negatively affected.
In contrast, look at this:
See how we fared against Studio MDHR's delightful-looking (and difficult) platformer. [Spoiler: We died a lot.]

They were able to experience more of the game in 14 minutes than Dean did in 26. They were learning on the fly too, so that's no excuse. They were at the same E3 as Dean was. The end result is a better preview that shows more content, (including the bosses) which is what people normally want out of a preview. Good for GameInformer.
