Overall I like the movie 🎥 However, the time threw me for a loop. There was no back log about where the time travel machine came. Except for a small detail “a old barn where the murder took place, and her dad's employee id” Then, it only showed the guy being bullied once, and a letter he wrote to a childhood friend (older sister) he never dated. What baffled me was, it was the 20th anniversary of the older sister’s death. The younger sister is clearly in high school at this point. To put it in context, the older sister had to be from 14-18 years old during the time of death (still in high school); placing the younger sister 14-18 (currently in high school) Therefore, technically, they aren’t 20 years apart. The sister should have already been born, ranging 5 and up. Math could be wrong 😑 . But I need more details lol 😂
