Is Anything A Greater Cinematic Achievement Than The MCU?

In terms of universe building; its the most successful and innovative, however it doesnt have many competitor's to compare with. To make a consistent 10+ interconnected film series does require great vision and stringent planning in execution. But not even 1 of the films can be considered an individual cinematic masterpiece so no way can it be the overall greatest cinematic achievement just for making multiple decent movies in a row. It just needs good dedicated planning which at the highest level of the Hollywood film making business shouldnt require that much of an effort.

Taking all that great vision and precise planning and using it to produce 1 or 2 top tier movies instead of 15 generally okay-passable movies is a better cinematic achievement.

If you asked this question to a film guild or film academics youd be laughed out of the building.
