The defensive Knack fans, angry or confused Knack "haters", and the video that looks like someone added a "2" to a Knack 1 gameplay trailer. Everything about this is hilarious.
Almost as hilarious as someone characterizing people who liked a game and are pleased it's getting a sequel as "defensive?" There are plenty of us who saw potential in the first game and are still more than willing to acknowledge that it was rough and needed work. The same can and should be said of many games without the extra layer of derision and condescension that gets applied to Knack.
