This movie dumb
I would have made the writer(s) do a rewrite. If I were a studio head I would never have given the green light to this monstrosity.
The biggest loose end, never confronted or cleared up, was why did the authorities not question the "Belkins" movers? They witnessed the idiot coming up the hill and jumping into the main character's car and driving off to his doom. This would have cleared Walter Williams' name. They (the movers) also called the authorities about Williams' suitcase found in back of their truck. It is dumb to think they would not have told them they were at the scene of the accident.
Okay, so you say, how would this have proven the wife had something to do with it? It wouldn't have!
Well, they should have never had this scene in the movie — because everything we see in a movie should mean something or move us closer to a truth. If it connects to nothing it is a waste of time and should not be apart of the script.
This film made no sense.
