I saw Tron when I was 10, and I thought it was amazing. I still think it is an amazing movie even today.
Why do people get hung up on stories having to have this amazing storyline to them. I love how vague parts of the story are AND how simple they are. Computers were much more simple then and to me it really reflects the kind of processing limitations and freedom of imagination at that time.
I can say that it completely influenced by desire to work with computers, work with animation, and more importably work with VR stuff while I was in college.
Are there movies with better visuals and better stories? Of course, but at 10 years old, I was blown away. I guess it really depends when you saw it as to how much it means to you.
And I agree, I think that is Chris Barrie (Arnold Rimmer from Red Dwarf) in the end of the segment. WAY TOO young looking to be David Warner AND the wrong color ! :)
