The answer is easy. The best of the three is "The Shawshank Redemption" followed by "Forest Gump" and then "Pulp Fiction". Why?
"The Shawshank Redemption" is a well rounded movie. It has a thoughtful theme and a great ensemble of actors. The story revolves around the false imprisonment of an innocent man and his resourcefulness and cunning to defeat an injustice under the American legal system. Many in America can relate to the main character's situation. Additionally, the actors all came prepared to work and hit their marks. lol The brutal life inside jail was shown and also how men bounded inside its walls. There is more to say about this movie but I am not writing an essay here today. lol
Tom Hanks' acting was superb and he earned his Oscar. But, the story in "Forest Gump" was truly a fairy tale. lol
I do not understand "Pulp Fiction", what is going on? I cannot determine the timeframe in the movie. lol
