Origins of the tape?
What has a dead girl in a well got to do with a videotape? Why nobody cares about the origins of the first tape? Who made it? How cut it? Who shot the footage?
Naomi Watts nicely wraps up the story of Samara, but how all this connected to the creation of the video? Seems nobody bothered by it... Characters and viewers alike.
(Noah does say something about the "fingerprint" of the recorder once, but never act on it)
I could say it's not important for the story pow, but the last twist with the copying puts the whole tape storyline back to the center again.
