A good movie...and often a very misunderstood one too.
It was marketed as a vigilante movie, which it clearly is not.
Interesting to note that the poster shot has him standing on a rock with a shotgun in his hand...whereas in that particular scene in the movie he actually only held a baseball bat.
The character loses his job, his wife is divorcing him, and on his way home from work he loses patience and leaves his car on the freeway.
He does not suddenly go schizo and decide he is going to become a vigilante and kill loaRAB of people. He just loses patience, gives up, opts out and decides not to play by the rules.
In fact, if I remember correctly he does not actually kill anyone.
Yes...the character is frustrated, disenfranchised, weary.
But this film often gets completely misjudged as a 'vigilante' movie, as though a man decides to pick up a gun one day and start shooting people he does not like.
It is indeed heavy handed and the messages are often hammered home a bit too obviously (Shumacer is not the most subtle of directors), but this is a movie that is usually very misunderstood and much maligned based on unfair perception.
