Couldn't get past the first scene with the hunters.

Seriously, are they ever going to make a movie or TV show that doesn't portray hunters as idiots or assholes? And what's the big deal about him being a dentist? Do they not realize that the millions and millions of people who are hunters also have jobs? Do they expect them all to be professional hunters? There's probably not more than a few thousand professional hunters in the whole world, if even that.
And then there was the bit about the .223 only being powerful enough to kill a squirrel! Ahah HAHAHAHAHAha ha heh ha! There's a whole lot of dead men that would beg to differ. The .223 is only about the most popular coyote hunting round in existence, lots of folks use it for hogs as well. And though it's not the most common deer round I know plenty of people use it where it's legal to do so. If you shot a squirrel with a .223 you'd waste most if not all the meat.
I don't know why writers don't do a little research when making their shows and movies. I mean it's not like this is hard to find information, it's pretty common knowledge. All they'd have to do is find a country boy and say "Tell me a little about guns and hunting" and they'd get more accurate info on the subject than 99.99% of all movies ever made.
