The constant smoking
Im sorry but as someone that graduated high school in 1987 and from college in 1992. Seeing the way the characters smoked didn't seem realistic to me. Especially since leilana and Troy were so against corporate America and their beliefs yet they sure as hell liked filling their lungs with all that corporate tobacco. They were supposedly smart and educated. If that were the case they would know how stupid smoking was during this time period.
The way they smoked it was like watching an episode of Mad Men
I can imagine 18 years later that leilana has lung cancer and sounds like Kathleen Turner and Troy has emphazema and is carrying around an oxygen tank still playing crappy indie songs with his crappy band.
