You go away slack-jawed with shock and sated with the chilling bedtime-story elements of a great unsolved mystery novel you can't put down.

Though the movie doesn't use real names and the press notes say it's "inspired" by the Durst case, it seems to follow many of the facts rather closely -- all the while mixing in not a little provocative speculation.

It's not the smoothest thriller. But All Good Things is thoroughly engrossing, a roman a clef that chillingly ponders a puzzle and suggests solutions outlandish enough to be stranger than anything Hollywood, on its own, could make up.

The result is a potent and provocative movie that will keep you up nights.

The film ends up wrestling itself into a corner, though it's saved by a corrosive central performance from Ryan Gosling and a disconcertingly hypnotic feel.
