My edit will do...

The mystery plot makes no sense. Won't exist.

The plot structure dissolutes any possibility for tension, and is so jumbled and weird that it's hard to RE-structure into anything different at all. It has a more straightfoward structure, but giving the film tension is going to be hard. If there is any more tension, it may be stuck in the politics.

There isn't enough with the Lars Family. Can't do anything about this.

The "forbidden love" subplot is too stupid to leave in, but too major to leave out. I'm still debating on if they're love should be forbidden, it's more an issue in Episode III if it can be changed.

Seriously, the hell is with that mystery plot? Again, won't exist.

The Seperatists and Dooku are the main villains, but they don't appear until the very end. And Dooku dies within the first few minutes of Episode III. He has no time to be a major villain. While there isn't much new footage, their appearences will be spread about.

Seriously...the Clone Mystery Plot. SERIOUSLY. Again, won't exist.

The effects are horrendous. Just horrendous. Even Episode I looks a million times better. Hopefully, the intense colour correction and 35mm conversion of the film will help.

Those are the UNFIXABLE things IMO. So...fellow OT-Ians...

How would you fix these unfixable things in your respective (or theoretical) fan edits? So I think most can be fixed, and at least others can still be drastically improved.
