Asking this question is just looking for passionate rants. That being said... The truth is pretty simple. The Agile Manifesto makes a ton of sense. Formalized Scrum or other processes are in opposition to what it proposed, so they are a mess. Informal processes developed by your own team, maybe based on ideas from methodologies can be effective. But you have to listen and adapt to the people on your team, creating something that works for all the stakeholders.
