I first saw Tron when I was a young child, and loved the colours, style and of course the action with the light cycles etc. Now I am older and understand the conceptual representation of humans inside a machine, fighting against computer programs represented as other people, I can see that The Matrix owes an incredible debt of story to this film. Tron stood completely apart from the time in which it was made, and tried to communicate ideas about computing that few people really understood, whereas The Matrix embraced the time in which it was made and presented the ideas in a way that the mainstream could come to terms with, but both are really based on the same premise.
Tron deserves to be viewed and held up as a brave, visually stunning and, for the time, incredibly high concept idea that has stood the test of time. Yes the graphics and effects are dated, of course they are. Is Jaws a bad film because the shark looks like a rubber puppet? The sheer quality of film making does not tarnish with time.
