I loved how this movie ended. And for everyone saying it's cringe or VR chat, this is set in 2002. There were no VR sets, the Internet was in its infancy. At most we had AOL and compared to day, even that wasn't that great.
People chatted with each other in chatrooms, maybe they developed a friendship from common interests. But there was nothing telling who a person was behind the screen. No screen captures, no cell phones; you're lucky if you had a laptop.
Maybe you don't understand because you were never placed in that situation. Maybe it's because you weren't around during that era or you were too young.
