Agreed. That sort of setup does suck. But then again that sort of team isn't really doing Scrum (they're certainly ignoring the way the roles should work, and they're certainly not using the sprint retrospective to improve).
This isn't Agile sucking, or Scrum sucking. This is folks not doing Scrum sucking.
The issues that caused the OP to move from Scrum to a Lean approach - I can go with most of those (indeed they match my observations of some other transitions)... but the delivery one doesn't ring true in my experience. I've seen a bunch of Scrum teams with a laser like focus on delivery.
