Avalon (2001) is a live action film from Mamoru Oshii (director of Ghost in the Shell) on the theme of immersive VR. It's in English, despite being a Japanese-Polish co-production. I liked it, though it might be to everyone's taste.
Thematic SPOILER ALERT: Lay off your video games for a bit and go out side in the daylight and smell the roses and hear an orchestra.
