Yeah, I think I'm smart enough to make up my own mind about things.
Even this NeoGAF thread is helpful.
I know GAFers have no problems calling them out when they're playing it wrong, or fail to show off some crucial gameplay point.
My taste in games is very different from the Giant Bomb guys, so its not uncommon for me to like games they won't. I have no interest in first person shooters and fighting games, for instance.
The value of the Quick Looks to me is introducing me to games I would not otherwise have heard about, and seeing some basic gameplay.
I've purchased a number of games they actively disliked because I liked how they looked and played.
I had never even heard of Nier until the Quick Look. Brad was fairly down on it due to the repetitive gameplay, but I knew it was a game I would enjoy right away.
Other games like Ghost Trick, About a Blob and You Don't Know Jack I had no initial interest in. However, after watching the Quick Looks and seeing how fun they were I've bought and played through each of them.
