SILENT RUNNING

This movie watched when I was in my twenties brought out more emotion then my ten year old self seated in the cinema as E.T dies. What's your thought's on this movie ? Personally it's hovered at the top for me out of the thousands of movies and TV shows I've seen and as a massive crime fan it's touched me deeper then expected. Let me know your thought's or is it just me that feels it deserves more recognition.
