Missing is not that good (or it hasn't been yet, I may revise my opinion once I catch up), but it hits a lot of my favorite things: angsty ex-spies whose pasts won't let them go, combative women with guns, parent figures, pretty European cities... It was filmed in Europe, and it looks amazing.

This season is only going to be ten episodes long, so it wouldn't be that difficult to give it a try. Basic idea: Becca Winstone used to work for the CIA; now her son has been kidnapped and she's trying to get him back.
