Not that it matters, but in the outline a Klingon ship shows up above the colony world and there is indication that the Klingons were involved in weapons and might have started war. Some cat and mouse with the Klingon ship like TWOK and TSFS with Kirk having an opportunity to destroy Klingon ship but tries negotiation. Looks like Klingons are hell bent on war. When Marcus shows up Enterprise could act to protect Klingons. The Klingon ship is nearly destroyed and knocked to side and forgotten as they deal with Marcus and Engineer. We understand and have some sympathy for everyone's motivations. Marcus saw crew needlessly killed and Klingons were poised for immediate war, Engineer was used and prevented from saving his family, Klingons trying to protect their colony in the neutral zone and subjected to outrages.... Try to keep everyone guessing for as long as possible about whether they are right or doing wrong. Twists and moral dilemmas. The primary purpose of revising the script of a movie already released is to increase confidence in the possibility for improving and learning techniques for doing so.
