I agree, I think the judges are way too harsh, esp at the very beginning!! Sometimes it's enough to make me not even want to watch anymore...they way they treated Michael Bolton last season was (IMO) sickening and changed my opinion of (and respect for) these judges forever. Constructive criticism is one thing, but tearing a person down the way they sometimes do is uncalled for.
When you don't like a thing, change it.
If you can't change it, change the way you think about it.
