Scrum is a tool for product development that uses transparency and fast feedback. The Sprint Review is an open meeting during which the Scrum Team works with all interested stakeholders to look at the results of the Sprint. This meeting is usually dominated by a demonstration of the working increment of software. The stakeholders in attendance at this meeting freely provide feedback about the product which is then used by the Product Owner to update the Product Backlog. This feedback is critical to ensure that the team is staying on-track, that it is building the most valuable possible product features, and that the stakeholders are satisfied with the results. Missing this aspect of feedback makes Scrum only modestly better than non-agile approaches to doing work and should be considered a critical problem to fix as it undermines the whole point of doing Scrum.
