Video reviews are short. They are often abbreviated versions of full length written reviews. The GT review of Skyward sword tells you mostly negatives because those are more important than the good things. BTW, I watched the review and didn't think it was negative. I was actually expected a score closer to 10 by the time the review was over so I was a little surprised GT gave it a 9.1. If you read the full written review on IGN you will see everything that got left out of their video review.
It's like a movie based on a book. An 800 page epic gets reduced down to a 90 minute blockbuster. The important stuff might still be there, but most of the detail is missing.
My suggestions, stick to text if it matters to you and watch video reviews when it's less important to you.
