There are several different types of slides, and understanding it's purpose is the key success and agreement. At the very least I coach my team to think are these presentation slides (fee bullets, some visuals, focus on the speaker), vs are they or will they become reference slides, which will be read by people not at your presentation or some time later. And there's my all time (/s) favourite, project management by slides. I found it (eventually....) futile to rage against corporate culture of misuse of slides for purposes other than presentation. That's likely where your disconnect lies though. Hope you have better luck than I did long term!
