The Evidence
Maybe I missed something but I've seen this movie twice and paid careful attention both times.
The whole point was to get proof that Dillinger stole Flynn's work and called it his own and Flynn needed to get the files to prove it. At the end, a printout clearly states that Flynn wrote the original programs. Yay! Except...
How is that proof? I could get my computer to print out a sheet that said I invented ketchup but that doesn't prove that I did. How is a single piece of paper going to prove anything?
I don't know much about copyright law, but it seems to me that Flynn needs to show conceptual plans and notes that prove those games were his ideas. Besides, if the games were so important to him, why didn't he keep a backup at home? For that matter, wouldn't there by written material (sketches, notes, etc.) that he would have at home?
Yeah, I know, it's a silly movie. But the premise doesn't make sense to me.
