I had the same experience first time I saw 弹幕 (dàn mù) aka "bullet screen" on Chinese video websites like Bilibili. If you haven't seen it before, it's like user-added subtitles that go flying across the screen while the video is playing, and in parts of the video where more users commented, more subtitles appear. In the most climactic scenes the screen gets so filled up with text that you can't see the video any more, and somehow that makes the scene even more epic. The future is now, chummer!
