The master spy codenamed <Twilight> has spent his days on undercover missions, all for the dream of a better world. But one day, he receives a particularly difficult new order from command. For his mission, he must form a temporary family and start a new life?! A Spy/Action/Comedy about a one-of-a-kind family!
Does anyone actually like SxF?
I thought it started out with a great premise with all 3 family members having secrets to hide from each other with good reasons, but as the show went on, it completely dropped the premise in favor of wholesome family sitcom with standard spy stuff.
And I didn’t find the comedy that fun.
Yes. I do. I assumed it was always going to be a wholesome family sitcom. If the spy plot advances, the show is over.
Definitely wish it had more advancement in plot but it’s still enjoyable. Plus my partner does a burlesque act as Yor.
