This is the second 'documentary' I have seen in the last few weeks where the filmmaker just strings along a bunch of clips about the subject.
Rather than explaining the Y2K issue with some sort of narration and context both at the time and looking back some 24 years later, the documentary relies on the clips from the times in order to do so.
All they did was compile news clips, movie clips and anything else from the late 90's that had anything to do with Y2K, present them in chronological order, and then add a few graphics here in there. Lazy and boring. I'm surprised HBO didn't just bury this.
