I kinda don't get the whole thing about ISOs. But other than that, I really enjoyed this film. Love all the action
***********SPOILER************
As best I could tell, the ISOs are sentient programs that were not coded by any user - according to Flynn's dialogue, the conditions in the system were simply correct for them to come into being, analogous to life on earth if you are a fan of the "evolution from primordial soup" theory.
If you look at the Tron mythology established in both movies, the users are the creators (Gods) to the programs, who are aware they were "built" by someone outside of their world. The ISOs, on the other hand are the miracle of life without creation - their digital DNA was formed without any input from an outside source; once whatever conditions that were necessary for them to come into being were met, they simply were.
How that works is left up to the audience to decide (for now at least, since I assume they'll delve a little deeper into this issue if a sequel is green-lighted). I like to think the primordial soup analogy is a pretty good example. On earth, Chemicals were present in specific proportions that allowed cells to develop and begin working with each other, and over the course of millennia evolved into life as we know it. In Legacy, I imagine algorithms and bits of code, perhaps from old/deleted AI software, sitting in a recycle bin on some long forgotten portion of the grid linking up and working together to generate the ISOs' digital DNA (just like early cells) in order to "birth" the ISOs, although on a infinitely faster timescale due to the difference in the nature of digital vs analogue (biological) systems.
Anyone get a similar vibe?
