I'm confused about the audience for this show

I've finished the show (Spoilers) and overall I enjoyed it but really unrealistic details have always been bothering me the whole time I've been watching it. I mean just random little things really, like what comes to mind: the whole time in Alaska I couldn't stop notice ng how somehow nobody's nose was ever running or anything, and when Wendy was yelling out into the landscape looking for Bear after she flipped in the vehicle, instead of obviously going and looking in the vehicle for her?? It feels like the writing and effort of realism/accuracy is reminiscent of a young kids' series. Which honestly would be fine, if that's what they were going for on purpose, but it's rated tv14 I believe and simultaneously has a lot of more mature themes of death and violence. I just wish they put more care into making the writing realistic, because these silly things are extremely common throughout it and really rip me out of an otherwise impactful story, taking away from the message.
