I'd appreciate if "this code is garbage" was at the end, so it would be (and feel more like) a conclusion.
Saying that stuff at the beginning only clutters the reasoning, as one should not "just believe" that that code was "indeed garbage", just because he said so.
That's a fair point, and moving it to the end would likely make the whole thing read better overall, but really... it's just not necessary to include it at all. It doesn't add anything to the discussion or critique, and can only serve to detract, so why bother?
