I like WS's intentions here. It's the artistic road of evolving yourself. Writer charlie kaufman wrote the incredible 'eternal sunshine of the spotless mind' and then he matured and made Synecdoche, New York and arguably more heavy handed film that intentionally lacked the vitality of ESOTSM. This is a bad comparison at first glance, since epic mickey is a traversal into "childrens imaginations via an unfortunately conventional means" and SNY was the polar opposite. However I find both to be elementally similar.
It's the creator of something exploring a side of themselves they earned. Warren likely takes a lot of this from connections of love, and CK more is weary eyed journey.
My problem with this artist evolution, is that I generally find the 'younger less wise' approach to construct new ground - and these 'evolved' approaches feel like more of a whim.
Deus ex stands as one of the greatest games of all time, and I would argue ESOTSM is one of the best films. Does this mean we need new talent to further innovate? Possibly. I always hoped that a man of 40 or 50 could be that same youthful innovator.
Well.... I did like eyes wide shut. There is always that.
