I haven’t seen TRON in decades, literally, so any memories of it weren’t fresh when I DVR’ed TRON: Legacy recently.
The temptation is to regard the movies as some sort of allegory about how computers operate. Sadly, that would be a mistake. Even if giving programs and fragments of programs anthropomorphic avatars makes sense somehow, the actions these actions take makes less sense. Racing light cycles and having one avatar die if its lightcycle hits the wake of another? Is that like having a programs memory space “stepped on” by another process violating its memory boundary? What do those flung discs that can shatter a program represent? Encrypting a block of memory so a program can no longer be executed in some meaningful way? Riiiiight…… Don’t even ask me to make sense of a program “mounting a lightcycle.” What is that, making a call to an on-board controller, like a graphics card?
On the other hand, if you think the movie was just a neat excuse to do some exercises with computer graphics, I can just suspend all disbelief and watch the pretty line drawings go by.
There are so many differences between avatars, you’d like to think at least the larger differences are meaningful. (An opaque face shield? Why does an avatar merit that?) Better still that you try not to think at all.
