Assuming we are talking about boring slides with just a few bullet points, then 99% of work is actually creating the (text of the) presentation. Creating boring slides can be done in a few minutes. Most time when I see a wrong and overful slide deck, people don't actually have any idea what they want to say. They just dumped some information in the slides that might be handy.
