*SPOILER ALERT* Trailer looked so much better than movie

So I finally watched PA3 and while it had some decent moments and some bonafied holy sh*t moments, after watching the trailer I was disappointed. I thought that since I watched the Unrated Director's Cut, I would see most, if not all of the stuff that was in the trailer included in this cut but it was STILL a different movie. They told the story showing the wife Julie not seeing much and not wanting to believe anything she was told until about the last 15 minutes, but in the trailer she witnessed a lot more and probably a lot sooner. So damn, is there yet ANOTHER cut that has so much of that stuff from the trailer or just deleted scenes on the BluRay/DVD? Yeah that was pretty wack they way they cut this. It could've been much better with some of the footage they had and didn't use.
