Plot hole: Johnny's dad jumps in his truck and gets to Johnny in moments. That same journey was shown to be an overnight bus journey for everyone else.
Plot hole: Lea has a criminal record, which includes theft. Lea told Casi, "You know how hard it is to live with a rap sheet hanging over you? How hard I had to hustle to even get a shit job at the tow pound?" Later, Casi made a reference to "most thieves" and Lea responded she's "not like most thieves." The tow pound is operated by the NYPD, so it is extremely unlikely that Lea would have been hired given her theft record, especially for a position that handles money/cash. (00:19:45 - 00:35:25)
Plot hole: When Alana is backing up down the hill after running out of gas, she passes a single story house on the left which has an obvious motion detector light on the front of the house that triggers the light to turn on as her truck passes by. Motion detectors of that type were not around in the seventies.
Plot hole: Kyle got a flat tire and there was no cell phone reception to call for help, so he and Julia decided to walk to the Ghost Town. However, almost all vehicles - especially a relatively new SUV like Kyle's - have a spare tire. Kyle surely had a spare and could have at least tried to change the tire himself. (When Kyle saw his damaged tire, he complained that it was a $300 loss, not that he did not have a spare tire with him). (00:04:55)
