Except you know, the Germans didn't even attempt to attack it thus Maginot successfully did it's job.
The French Failures were not Maginot. But their deployment towards Belgium. And most importantly the Battle of Sedan. France with what it had at the time could have won Sedan, and should it have won it then the Fall of France wouldn't have happened. Multiple officers were to blame for that happening, none were ever put to trial for what they did.
This video does a decent job explaining how they fucked it up.
