I just read Snodgrass's original script for Ensigns of Command. Very good, but I liked the episode as aired better. The romantic part didn't feel like it fit. Hrathans were changed to Sheliak, a change I liked.
Interestingly, the coolest parts of that episode were not explicitly in the script:
"That was the stun setting.....this is not." and Picard checking the Enterprise plaque for dust. The conclusion with Data and the aqueduct was much better in the episode I thought.
Snodgrass's legal background lent itself to some good episodes involving laws and treaties. As good as The Drumhead was, I bet she could have made it better.
