I dislike agile and scrum not because I think they're bad ideas - in fact, there are some good ones in there. The problem is they're so doctrinaire. A "manifesto", scrum masters, agile consultants, etc are all there to enforce processes that don't always make sense for any given team or organization, and they detach you from the reality of actual productivity. Didn't assign the right number of points to your scrum story? Didn't break things down into tasks properly? Velocity fail? If these are your problems, then you're focusing on the wrong things.
