Query: A Tired Plot Slower than Molasses in Winter...

My wife and I watched the first hour of this leisurely "thriller" before calling it an evening. Neither of us could jump into the characters, all of whom were too selfish to love and too banal to admire for their rottenness. The plot itself was confusing (and this for a pair of movie lovers who predicted the endings for such films s Sixth Sense and The Prestige) and SLOW in its front and back stories. No doubt the ending saved this film (as well as decent acting and direction), but you'll have to slog through a good hour of excruciatingly sluggish "build up" with two-dimensional characters to reach the pay off. We didn't have that kind of patience... .
