If you give feedback that isn't constructive your feedback is worthless. I know that sounds harsh but it is. If you give unconstructive feedback you might as well not be saying anything. If you just look at something and go "That's stupid" or "I don't like that" - that's worthless feedback, nobody can do anything with that. They're not going to start throwing darts against the wall until you say "Oh OK, I like that". You have to say something more.
