We have the right to criticize. Criticizing is an action. Words are loud when they are heard by many. If a choice is defended by a vocal majority,this doesn't give any proof at all that this choice is the right one. You don't need to be an artist to see if a picture is poorly drawn;and in the same effect,you don't need to "do better" to voice your opinion on something. We do not all want to spend or waste time learning how to make sprites to voice our discontent or prove a point.Each one's their hobbies.I do art.Others do knitting.Some do spriting.I can still say I don't like a piece of knitting or spriting,and they can still say I cannot draw straight.
