As a creator of stuff myself, yes, it can hurt to receive criticism, but as far as I am aware, Internet Kraken only offered constructive criticism, with suggestions as to what to do better. I am not aware of him simply lashing out with something like "This sucks and you're a n00b." The first is trying to help you, even if you think it hurts, the second is simply judgmental and not helpful in any way. Personally, I don't find this series funny and I stopped watching it partway through the second episode. I also didn't watch Pokemon or Yugioh, so the humor, no matter how good it is, doesn't really appeal to me.
But reading the comments here, I think that the creator on this one has to take his big boy pill. You might get 100 people telling you how wonderful what you create is and how every line is a diamond sheathed in gold that has dropped from your lips. That's fine, and it's always fun to read. But it's the constructive criticism that will help you get better. Don't dismiss it out of hand.
