Summary: I bought a set of Kenda Kriterium tires based on the reviews listed here. Having ridden on them a few months, I can say that while I don't disagree with the other reviews I definitely think they didn't give me a full picture of the tires.
As the other reviewers mentioned, these tires are stiff and tough. I'm not worried about getting flats out in the middle of nowhere and don't have many fears about rolling them off the wheel in high speed hard turns.
However, that stiffness comes at a price. The second I put these on my bike I felt immediately slower. It felt like my rim was rubbing against a brake somewhere; I just didn't have the same jump and acceleration as I did on my previous Vitorrias. Basically the stiffness of the tire increases rolling resistance. For an explanation from an expert, see Howard Zinn's take on this kind of situation here: http://velonews.com/article/85518/technical-qa-with-lennard-zinn---fight-flats-lose-speed
Now, if you're commuting or just a recreational rider I think these tires would be fine. They're inexpensive, durable, and can be ridden in wet conditions. If you're looking to keep up with a hard-charging group of Cat 3/2/1's you'll want to look elsewhere. I'm actually going to keep these on for training over the winter simply because they make me work harder. By the time spring comes around and I switch out to something more supple, I'll feel like I'm floating along my Cat 4 races. Strengths: Durable, okay in wet weather, relatively inexpensive. Weaknesses: Increased rolling resistance compared with other tires means you'll have to work harder for the same outcome.
