The problem is, where do you draw the line between someone who honestly, earnestly, tries their best and fails and someone who really is just all hype, all the time?
If he were the PR machine many people (justifiably!) think of him as, I'd imagine he'd be quite pleased with the not-terrible reviews. His stance seems to be, "this was good, but we can do better!"
Whether you actually believe that's his aim or not, I will always wholeheartedly support someone who says that in the gaming industry; I think it is what more developers need to hear.
