I think you guys care more about the length then the content. They put more fighting footage in, stuff people complained about not making it in when the second movie came out. I mean, it was nice to get extensions of the fights, but some of the new CG footage didn't look all that marvelous.
I mean the Jameson bit was funny. The Vanessa Ferlito scene was OK. But the other alternate version of the elevater scene works no where near as well. There's a lot of other extensions, lines, beats, and bits that are restored and they don't really add that much.
The doctor scene. To me it changes the tone of the scene. Because when I first saw the scene, I thought, OK maybe this is like Peter's regular family doctor who he's seen before, and it's like Peter is visiting a guy he's met before. But in the extended version, the doctor I think turns out to be I think a university clinic guy, and it's clear he's meeting Peter for the first time. You see I like it the other way better, because it lets you infer a lot more about the character. I think the longer versions tells you stuff that really isn't important, and it's still just as effective in the theatrical cut.
