Flashy 10-Ks are hugely annoying, especially in IFRS where there’s no standard. Give me tables all day every day. The lack of standardization in financial reporting already sinks enough of my time.
The application of XBRL doesn't really affect the design of the reports. It ebbs and flows - it feels like more designed filings are coming back with better tools that allow more designed reports.
I hope things have improved in the years since but I doubt it. Nobody looks at the XBRL its just a regulatory box tick.
