If you missed the releases there has also been an extended L.A. Story and a restored edition of the Little Mermaid.
As far as a true fan edit goes, I'm still looking for the right project.
Star Trek: TMP was promising, but it sounds like a lot of people are jumping on that one (finally).
I was recently really furious with the ending of L4yer Cake (though swapping an ending isn't a very serious change).
Honestly, I don't know, the Matrix was just something I was really emotional about since I consider the first film one of the greatest of all time.
It's like there was a Casablanca 2 and 3 and they starred Ben Stiller and Drew Barrymore or something. Ok maybe not, but I felt they had to be completely dismissed, or rebuilt.
I haven't come up with another movie I've felt that way about... yet.
Maybe I'll rewatch the Whole 10 Yards.
