No verisimilitude
So the opening shot... a subway car comes into a station, and the doors open. Only then does our heroine look up, close her book, and very casually stroll towards the open doors. She stops, sees a bag, strolls up to it, takes it without asking if it belongs to anyone, and gradually makes her way to the door.
That is NOT how the NY subway works. If you're still reading your book when those doors open you're not getting off the train.
She then finds a NYC Identity Card in the bag.
A what now? Where do the writers thing this is, East Berlin?
She then goes to the subway lost and found booth.
No, really. A NYC subway lost and found booth.
At this point I gave up. Why waste the next 90 minutes on something its own creators didn't bother with?
