Most of my teams problems with Agile/SCRUM come down to skipping steps or not following best practices. Once we fix those, it gets better.
If you read the agile manifesto, there are no specifically prescribed steps or rituals, and in my experience, most teams implementation of scrum is entirely counterproductive to actually being agile. The core tenet of being agile is essentially people over process, and things like daily stand-ups, extremely formulaic retrospectives and backlog grooming meetings do nothing to empower the people and allow them to be truly agile.
