1. No Leonard Maizlish involvement in the show (beyond his legal work/contract negotiations for Gene R).
2. Remove the overly dramatic music cues just before commercials for season 1.
3. Substantially re-write or change the first season's episodes, and a good slice of the second season. That would have been difficult given Gene's state of mind and perspective, but that is what I would change nonetheless.
4. No firing of Gates McFadden.
Other than that, there is nothing major that I would change about the series.
