The best version of Agile I've ever been part of didn't start great, started like what you describe. And everyone hated the day long retro and planning. So we iterated over it until we got people to come to those meetings with their homework done and tasks reasonably thought out and split instead of having to waste everyone's time for it. And in the end it worked quite well. Retro and planning down to ~1 hour. I will fight, in any team I'm a part from now on, to avoid the interminable scrum rituals. They are soul crushing for most good engineers I know. I never ever want to do them again.
