What is it about 'Back To The Future' that makes it so endearing? I've always thought it's the idea that no one's future is written yet, and we all have the power to change our own destiny.

Me thinking that doesn't say much, but coming from the mouth of Doc Brown himself, you can't argue. Listen carefully to what Doc Brown, as played by the wonderful Christopher Lloyd, has to say. Happy 'Back To The Future' Day everyone! Make it a good one!
