Dexter Original Sin sounds different to me

Maybe I've changed since watching the original Dexter, but the actors sound different to me now. In the original Dexter, the actors sounded like real people. But in the new series, the actors sound like they are reading a script or something.

The characters seem cartoonish, for example with Masuka "thrusting" at a colleague. Did people do or tolerate that in the 80s (or whenever this is taking place) outside of a grade school?

But mostly it's the way the actors speak that seems off (with some exceptions) And I don't mean the accents.
