I must say that mcfly89 has done a pretty good job at combining the best versions out there. And of course he's right when he says that someone has to do a fanedit because there is just too much in there now.

The little feature about wider is worser is ... well lets just say is disagree with it but I wouldn't have cropped it either, but for different reasons. The funny thing just is, that in every (and I mean every) scene that you listed as an example how much more you see in open matte, you also see that the only thing you see more is dead space ;)
Look at the scene where the girl runs to the camera. You see her being followed by the main supporting actress and only in the Wide version you see that the camera is actually following her. We are supposed to put our attention on her and that just doesn't work in FS because here you also see the face of the other woman.

But on the other hand, the matte isn't centered and even seems to move during the movie and it would be a bitch to keep track of it. Too much work for this preservation project. And also the resolution is already only NTSC, and cropping it and zooming in will just make it Babylon 5-like crappy. So fullscreen is okay but widescreen would be superior - if there was a suitable source.

Where you are completely wrong however is the BTTF example though. Unforgivable ;)
The wrong cropping in BTTF 2 & 3 came because they took a fullscreen master tape (which already had the cropped wide to full composite scenes) and then cropped it. Of course the framing would be wrong then, it's cropped twice now!
When they fixed it they went back to the original negative and took the original widescreen composite scenes which were matted correctly.

However, I did not want to rant or something, just offering my opinion. I like the job you have done, and I didn't even zoom in on my HDTV.
