I have to admit I would rather have some kind of feedback than none at all.  Sitting at your desk wondering if you are doing a good job without any indication from your boss, is not healthy.  If I was wrongly criticised I would try and find out all the information, who is doing the criticising etc and try and ascertain what went wrong and how to fix it.  After all you cannot grow and develop your career if things are not right along the way.  It's better to receive guidance and help along the way so we can change things for the future.
