Script review - "Girl on the Train" by Erin Cressida Wilson (warning: spoilers)

Excellently written script by Wilson, who I'm now a big fan of - the big print is a pleasure to read, the structure tight, the dialogue engaging. Everything in it has been seen before but the combination of it keeps it fresh - someone observing on a train, alcoholic hero who doesn't know if she killed someone, cheating man, unreliable narrator, cheating shrink, infertility and loss of a baby. It's really well done.
