The prequels have good ideas, but I don’t think there’s enough workable material in the prequels themselves to craft good movies out of them. Perhaps you can edit them to make them better, but the same’s true about Highlander 2, and the alternate version of that film still doesn’t rise above mediocrity.
Perhaps a radical re-edit of the PT will be made one day and my mind will change. 'Til then, I’ll stick with rewrites.
