One Man's Plain Modern Jargon

In the post...

...The story centers on a rebellious cat with a protective owner, who sneaks out at night...

The cat is rebellious but the owner sneaks out at night? (Okay, the "with" clause makes that not entirely a construction error, but I had to say it anyway.)

...1990s slang in the mouths of 1940s characters...

Can't think of any examples offhand, but that is one that has bothered me sometimes, when I am pretty sure some usage was developed later.

Thinking of just having seen a trailer for "Risen" - even in ancient historical settings where they're all speaking "English" so you have to allow some leeway, use of some modern phrase will be jarring.

Of course, one man's plain modern jargon is another man's inappropriate hip lingo.

And in the comments:

Seamus Muldoon: I've said it before and I'll undoubtedly say it again....

It's sad how Muldoon has run out of new material. May have to change his name to Seamus Rubio.

I'll tell you what I've been reading, but, have to go feed the pets first. BBiaM.
