Sorry, but those "good loglines" kinda suck. The second and third completely fail to tell us what the hero is spending 110 pages trying to accomplish.

If a logline does not include the task that must be completed in order for the story to conclude, then it is not a proper logline.

You cannot accurately describe Jaws, for example, with a logline like this: 'A killer shark terrorizes a beach'. You have to include the part about the hero trying to stop the shark, which is literally what Jaws is all about.

The active, physical pursuit of a specific goal is the #1 most important part of a logline. If you don't have that, then you don't have a good logline.

I agree with Ryan. They were not that good.

I've been told loglines should have a protagonist, their goal, an antagonist and the hook.

The hook being what makes it so different than any other derivative of a similar story.
