I enjoyed this psychological drama. It would be wrong to call it a ' psychological thriller' or a horror film, although there are one or two images (hallucinations, assorted demons, realistic war scenes) that some may find disturbing. And there is one section in the old hospital where the central character is taken on a wobbly wheeled trolley past some quite disturbing scenes...
The film tells the tale of one Jacob Singer (well played by Tim Robbins) a US postal worker and Vietnam vet who begins to suffer a series of bizarre hallucinations that lead him to investigate what happened to his platoon back in 'Nam only to be trapped in a bizarre conspiracy theory and yet more hallucinations.
I won't reveal any plot spoilers but suffice to say that the film's title gives the game away (if you know your Bible, that is).
I found it excellent, but I will mention two points that I didn't like: the worst is an (uncredited) appearance by a pre-fame Macaulay Culkin in an awful simpering role as Jacob's son, killed in a traffic accident, the other is that I found that Tim Robbin's too-easy smile didn't seem to fit well with the haunted character he played. But these are minor points.
Excellent - 4/5 stars. Recommended.
