Our War Game (2000) // Summer Wars (2009)
I never did understand this
The comparison? The left side of the screen are clips from the digimon movie, the right is from summer wars which was made several years later and featured a similar plot. Evil sentient computer virus infects internet. It messes with public services, email, phonelines, ect and causes a major threat. Heroes gain power from other people online to turn into their “mega forms” and fight said virus. Fight ends with the nerdy computer character dramatically hitting the enter button.
