What begins as an engaging but slow-paced (lots of long driving scenes) supernatural-tinged mystery comes to a tragic climax unexpectedly early, setting the stage for a uniquely extended and deliciously eerie epilogue dealing with the devilish psychological aftermath. The doppelganger intrigue could have been dragged out a little longer before the shocking twist reveal, but an excellent thread of torturous dramatic irony takes its place. A well-acted and surprisingly emotional thriller.
