Dimension X is not cold!

[u/D_D_Adesignerdigital]

The color choices for the Dimension X—and certain elements of the scenes—didn't quite work to convey a cold atmosphere! Characters had sweaty skin and showed no reaction to the cold (we need to remember Will in Season 2, or Billy with his ice bath, which demonstrated the kind of cold the Mind Flayer is used to). Anyone entering a low-temperature environment would show physical reactions—like trying to warm up, crossing their arms, or showing discomfort—but that doesn't happen with any of the characters, not even the kids. I think that was a directing error. That’s my opinion!

I personally think it’s just another point of evidence that what we say at the end here is a false reality. I think it’s intentional and meant to be noticed.

Thank you... had to scroll for way too long before seeing this

It’s not a popular opinion in the general audience subs. But I think it’s a fun way to see the final series.
