Should the Plot Summary be vague or detailed?

I have seen a lot of vague issue plot summaries recently that were obviously taken from the publisher's site. These summaries really don't 'break down' what the issue was about.

My question is, should the Plot Summary be an un-opinionated recap of the issue that may contain spoilers or a generic 2 liner headline?

They're solicits that are allowed add.
You can do both or either one. If there's already a solicit on a page, don't remove it and write your own summary without italics below it.
