Oh right, the domestic spying thing. If
Covert Affairs weren't so obviously goofy fluff, that might be offensive and disturbing.

Look, it's the American Gestapo! How charming!
I thought they were already working on Chaos
CBS was working on
Chaos and that one actually sounded pretty good (realistic, at least).
It came back unexpectedly from the dead for a midseason pickup.
Hopefully if Freddy Rodriguez launches into any domestic spying, the show will have the wits to acknowledge that as a bad, scary, unconstitutional thing and not a source of harmless fun.
For what ABC pays in producing a new show, why don't they just by the rights to air MI-5 in a late prime time hour and a half?
That wouldn't benefit the audience since we can all rent the show on Netflix. So why not do that and get ABC to develop something new (hopefully not a cop/doc/spy/lawyer show) for that timeslot. We get two shows instead of one and double the odds of something worth watching.
But since this topic keeps coming up, there's a good reason why studios remake shows rather than re-airing them. They want to find franchises that they can spin off forever and ever -
CSI,
L&O. But if they don't own it 100%, then they can't capitalize on it, so to give a prime time slot to something they don't own is a waste of good airtime. They need to use all their primetime slots to keep churning the waters to find that next ever-elusive hit franchise that will pay for their 2/3rd failure rate for new shows (and even among survivors, very few become franchises).
