This is a ripoff

You mean Spykids that's owned by Disney stole the idea from themselves whom probably stole it from someone else

And Spykids stole the idea from some other movie.

You heard of James Bond? Yeah, James Bond was a spy movie before Spykids existed. And there were spy movies before James Bond.

This last episode felt like an old episode of Batman to me, and that's a good thing. I don't know how long they can run with this storyline, but they have me intrigued.

Spy Kids is an original concept from director Rodriguez's mind and read the story to them at bedtime.

If you listen to the first 3 minutes of the audio commentary of the DVD.

So the OP is basically correct. It's entirely possible looking at the history of movies from the silent era, it's possible to find a movie or TV show that had it before Rodriguez.

Canada has "Connor Undercover" (Family Channel) while an action/drama with comedic elements, is better than a typical Disney sitcom. Worth a Wikipedia look.
