I haven’t seen any of the film or trailers.
However as to your concern that the character comes across “like a redneck good ole boy and badly in my opinion”...
The bottom line is the film is a smash hit.
Libs heads are exploding.
You should add that I said, specifically "sounding like... and badly......
I have no misconceptions that it is probably a very good movie, but I don't like actors who can't pull off accents trying to do so, and that's what the trailers I saw sounded like, frankly.
And what is wrong with a redneck good ole boy, may I ask when he is saving your ass.
