He pioneered that modern post production heavy flow for blockbusters, and everything listed is pretty common in that niche.

Honestly it's almost more notable these days when that kind of stuff doesn't happen.

You're basically paying more money to decouple and delay decisions as much as possible.

I've also heard this practice blamed for enabling a decade of "bad cgi"—visuals are reworked and reworked until time runs out, and in a rush they ship visuals that are worse than in movies 20 years ago. Explicitly: it's not the artist, it's a production pipeline failure. And indeed, it's easy finding marvel movies whose CGI looks closer to that of a video game than Lucas's prequels. Heck, even the sequel movies fall into this category.

Tech debt!
