The motion to screen for a property is always an interesting transgression but also has to do with evolution and context. "The Flash" is a mult-tiered beast, at once both nostalgia, moving and thrilling and yet with other points that are derivative and self-serving. Both have their own strengths and weaknesses and the movie succeeds more than it doesn't.

The texture of "Spiderman" reflects in who a certain generation needs him to be. The aspect of "No Way Home" indicates an existential crisis which the whole last film with Mysterio was built to set up into its final moments. "No Way Home" isn't a clean movie by any means and it could work just as well as a large scale series because of the literal way it works.
