There's a good Reddit comment here from someone who worked on authoring Blu-Rays that explains why this happened: https://www.reddit.com/r/IAmA/comments/1vdrbr/hey_reddit_its...
Essentially, authoring a Blu-Ray is complicated, and involves using expensive and proprietary authoring software to write Java code under severe RAM limitations that limit what you can do. Authoring a Blu-Ray from scratch also involves testing your code on a ton of different players, often with incompatible Java implementations. As a result, the studios just use the same simple menu templates over and over rather than creating new menus for each title.
Product design centered around corporate identity/branding did the rest.
I wish I still had access to it because looking now it was distinctly different from the actual release DVD menu.
* The IT crowd season 1 had leetspeak and base64 encoded subtitles (won't spoil what the encoding decodes to).
* Goodfellas has a commentary track with the central criminal and the FBI agent who arrested him.
* The Simpsons (around season 9 if I recall) has a hidden commentary track (not accessable by menus) where two of the writers fairly candidly explain the quality dip that was to follow, and have an impromptu phone call with the illusive John Swartzwelder.
I’ll have to check out the Goodfellas one though.
So no, I don't want animated menus or worthless features. Put a commentary track - that has high extra value to size ratio - but leave it to that.
