Typical 70's era supermovie. Poorly scripted and unrealistic scenes. I believe Steve McQueens 5 minute monologe in the last scene probably saved the reel from getting tossed into the waste bucket.
I saw it when released and actually watched a little of it over this past weekend. One thing that struck me was I forgot how long the intro sequences that showed all the credits used to be for a lot of the movies released at that time.
I remember taking our small boys to see it. Our eldest son was so nervous watching all the drama he kept wanting to go to the toilet much to my husband's disgust.
