I found it intriguing, and it kept my attention, mostly because it was clearly signally a 'twist' and I was trying to figure it out (I was expect it would be she got pregnant and ...). First off, if you were trying to find someone trustworthy with your life savings, and Mother's life, would you choose a passed out Drunk at a weekday matinee? Why not go back and trust your Mother or Father? Why not win the Lottery and bury the Cash? Where did she get the cash? Did she bring it with her, and if so, where did she get $80K of old currency? If she can bring money into the past, why could she not take the certificates into the future? She bought stock (who gives out stock certificates any more?), but they were gone from the box? Wouldn't they have to be there for her to get them in the future and save her Mother? She put the money in his bank account? Why and where did she get that money? Who removed the pics of her from his phone. If her, why did she put pics of them in the box? Clearly she existed, because the Bank Manager spoke to her. Some claim she saved him, but didn't his best friend tell him to take her to the Hospital? Not like she suggested going to the Hospital. If he dreamt the entire thing, then how did the best friend know about her when he woke up? ... and if we are not supposed to think about it, and it is a simple allegory, then would not saving someone life not alter the future, and wasn't the point she was not supposed to do that ... or was the point we are all meaningless ants? If the box was empty, and no cash added to his account, then she was a tumor induced dream that saved him; which would have been a better ending. Maybe the movie did not Test well, and they added the pics to the box to make it a happier ending, but ran out of ideas and money to tie the loose threads together?
