My conclusion is this.... the marvel formula is flawed.
The Infinity Saga was seamless, but post End Game, it's been a clusterfukk due to time constraints. These movies are announced years in advanced, but for some reason they drag their feet on selecting writers/directors and actually putting the movie together. This means less time in post production.
Then you have writers/producers having to wait to get input from teams producing other movies to ensure continuity isn't screwed up. Which leads to wasting time doing rewrites. So after spending all that money, they're trying to get it out as soon as possible to start making their money back.
It's why the TV shows aren't an hour long.
Some of these movies should really take 2 to 3 years to do, but they end up doing all of it within a year, which isn't practical.
Quality matters, There should already be a director and a writer for Fantastic 4 but they don't. No actors, no nothing. And it's supposed to drop in 2 years?
This Thor movie started production in January last year and ended in June. So they had almost a year to do post production and fix this bullshyt.
