Well of course you use your brain. You wouldn't be alive if you couldn't.
1. I judge things after having ample experience with said things. Anyone who has no or little experience with something has no right to pass complete judgement on it.
2. I form my own opinion based on my own experience with what I'm judging. Hearing other people's opinions first may sometimes lead to the implantation of certain thoughts in your mind.
3. "IGN, Gamespot and so on aren't really good reviewers either. They give far too high grades, and most people agree with that. To know if they're grading too high, you should read independent and unbiased reviews. That's how it goes." - General consensus =/= fact
4."Of course we're all entitled to judging things." - You said it yourself. We're entitled to judge things. We're not entitled to judge everything.

Dear Skydaddy... just the kind of reaction I would've hoped not to see. >_<
1. Of course I'll judge the game fully when it's released. However, that doesn't mean I can't judge what has been shown so far, including the demo.
2. If you can't rely on your own opinion, then don't listen to those of other people, as you will rely on those opinions fully.
3. I'm saying you need to read as many reviews as you can to know the full story. In fact, the general consensus is what IGN Gamespot and so on convey, not the independent reviewers like you, me and say, the people who post their own reviews on Gamefaqs.
4. I'm not judging everything. I'm saying you can judge what you've seen so far, which is what I'm doing. If the full game turns out to be spectacular, unlike the demo, I'll take back what I said. However, the game is only being polished now.
