'Girl On The Train Highs And Lows: Don't Take It 'Seriously?'

The trajectory of life toward catastrophe is what the blockbuster hit movie based on 2015 debut novel by Paula Hawkins could show us. Watching the "Girl On The Train" takes us into a long-winding journey of mystery, crime and thriller, but we should not take it too seriously.

In the report published by The Wall Street Journal, director Tate Taylor tells us how "finding humor in the darkness" works for "The Girl On The Train." With a suspicious eye, millions of readers might look forward to the dark character of the ex-husband Tom played by Justin Theroux.

But it's no surprise if the signs of his treachery might elicit laughter from the watching crowd. Asked the hilarious part of "Girl On The Train," Taylor had one thing to say.

"She's so good at calling him out on it, she lets him have it. It's just delicious... I read the book and came to the conclusion, and I went, 'She just stabbed him with a corkscrew? Oh my god!" he told The Wall Street Journal.

"The Girl On The Train" features the life of thirty-something woman dealing with life's idiosyncrasies. Rachel Watson, the lead played by actress Emily Blunt, just like anyone of us, is trying to move on from a recent failure and get on with life's atrocities.

The alcohol surely takes its toll on her, and clouded the thought of fatal fall and brokenness. Trying to preoccupy her thoughts and such hole on her chest, she takes a weekday trip to and from Manhattan, gazing out the train windows.

To divert her emotional baggage, she developed an obsession to passers by. She even documented glimpse of the picturesque relationship of Megan and Scott, whom she enjoys watching doing simple yet remarkable moments of love.

But little did she know that a maze-like journey for her is under way. Rachel could be the missing piece in the puzzle of a tragic love story when a girl went missing in the suburbs in "The Girl On The Train."
