I've only watched the bonus material so far. And that too, only bout half of it. I can already tell, the price I paid was worth it just to see this footage of screen tests, deleted scenes, and trailers.

I almost cried when I saw the trailer for GF3. I was young when it came out, so I didnt see it then, but I can just imagine had I seen I and II before, and then seen this trailer for III, I would have been completely overtaken by it. The bonus material rocks.
