If you view SCRUM as a rigid framework, you've already surrendered and completely missed the point of agile in general. Just because something was formulated once, does not mean it's not evolving and not improving with learning and new findings. It's nearly 30 years old at this point. The SCRUM guide is vague, and only provides basic roles, event, and definitions. The SCRUM alliance explicitly state that SCRUM is a starting point, and following the Shu Ha Ri principle a good team will eventually transcend the starting point. But you need to be disciplined when starting and learn it as it is defined. In my experience the main issue with SCRUM is actually with the team members. Either they're not dependable or too low performing to be give the freedom and self-management it requires to succeed, and management is not willing to foster the necessary environment and/or get the right people.
