When I was young I bought my first car which was very inexpensive. The purpose of this car was to get me to my destination. On my journey I didn't have much money for food, gas and motels. I ate cheap and slept cheap and certainly didn't drive a Cadillac, but I did get where I wanted to go.
The same can be said of this picture. With a limited budget, there were not the magnificent sets as seen in 'Saving Private Ryan' or mega star actors like Brad Pitt or Tom Hanks, and certainly the script could have been better written.
Having said that, the film maker did arrive at his destination also. No, not in the style to which we are accustomed. We should evaluate each film based on the story and budget and not base our criticisms on comparisons to benchmark mega-budget films.
This artist painted a fair portrait given a limited pallet of colors.
