Just about stays on the right track

Though not without its flaws, this mystery-thriller still works as a captivating, almost ghoulish, peek behind the curtain into lives that are nowhere near as perfect as they appear on the surface.

The deeply flawed characters are played with great gusto by a largely impressive cast, led by an accomplished turn from Emily Blunt, while an icy Rebecca Ferguson leaves you questioning her motives.

But the flashback-heavy plot doesn’t work as well on screen as it does in Paula Hawkins’book as The Girl on the Train movie fails to build on the solid platform afforded by its more memorable source material.
