I've lived in Minnesota my whole life and never heard anyone talk like that but it's hilarious.
Following the advice of the Nerdwriter, I tried focusing on shot length and cuts by making a tally for every cut. This was an interesting film to try this out on, as cuts were clearly avoided as much as possible. I found that there were roughly 485 cuts, giving an average shot length of about 11 seconds. Also, no fancy camera angles or movements were used, and there were no scenes without either of the girls. All this together makes the viewer feel as if they were there in the world looking on upon Amanda and Lily, which created a unique feeling of suspense.
