Haunted by a criminal hacking change in his youth, a genius highschool student revives those skills when he makes new friends and discovers a nefarious plot from Superman III (1983).
This movie is comically fun with enough nods to actual stuff to make it laugh-out-loud for its superiors. I don't know if (or how) I could recommend this to anyone for any reason. It's dated in every respect, unrealistic and cheesy with no sign if that's intentional or not.. yet somehow I enjoy it.
I'd say it's worth watching for anyone born in the late 70s and early 80s who was into tech in their youth. Even then it's a weak recommendation. For anyone else, pass. Just. Just pass.
