I found the Sol Levante AE project files to be a huge nothinburger. Like there's nothing there... it's literally just a background and two character layers, no effects or camera moves or anything that would be remotely interesting to a VFX person.

This feels to me like an intentional obfuscation-- like the studio didn't actually want to open-source anything meaningful, or netflix didn't pay them enough to justify collecting huge project files.
