I think scrum is a tool for middle management that invented ceremony to give their role "meaning". At the same time it allows them to avoid the difficult questions of product management (e.g. "is this really an orthogonal feature or does it interfere somewhere?") It also tends to be awfully childish sometimes (this management style was allegedly invented by pedagogists). Regardless, several techniques are actually worthwhile: Retrospectives for things that happen regularly (they aren't useful for things that happen very seldom). Daily standup as a sync for developers that collaborate the same task.
