Anything higher would be a travesty. Not sure if we are supposed to believe they have any previous spy experience? Basically two strangers are paired to make a super spy couple, who work and play together.
They bumble through each mission with no skillset, plan or tactics. Erm and that's about it. No character development, no chemistry between the two. Almost like each episode has been thrown together in half hour. Another big money failure that uses the name to trick you into thinking this is worth watching.
