yes! the story of the prequals CAN be fit into 3 films. It goes as:

Ep I- parts 1 & 2

Ep II - parts 1 & 2

Ep III parts 1 & 2

ie: HP:deathly hallows, and the upcoming hobbit 2 parter. Of course it has to be done with a writer/'director who can pour his heart and soul into it and actually gives a damn about quality, story, and performance and not just $$$$ from merchandise. There was plenty of time to carve out a storyline for something of this size between 1983 and 1997(or whenever shooting for EP1 started). Each part could be 2hr30min long. I think fans would love it, I know I would. I think the time alotted would be enough for tons of entertaining, useful, creative ideas other than the tripe we actually got.
