The first photography critique I ever recieved was from my college photo teacher on prints from the very first roll of b&w film I ever shot. He said "These are terrible, horrible, get them out of my sight!" Yes, he was right, they were, muddy, grainy, the worst.
When reviewing my work later on in the course, he silently went through the prints, pulled one out and said, "This is a masterpiece."
By next semester, I was his teaching assistant.
