I hated collecting all of those stupid blue coins. It tarnished the game for me when I got near the end and had to go on a scavenger hunt to beat the game. There were far too many (30 on each level) and they were scattered all over the levels on each and every episode, sometimes in obscure places (especially Noki Bay). I feel like the game would have better if they had added more levels and/or episodes to extend the game length rather than an annoying task.
Never argue with an idiot. They will drag you down to their level and beat you with experience.
