It wasn't bad but it wasn't good, either. The character of the son of the bus driver annoyed me especially when he perceived the other kids not respecting his father but even I could tell they did. Maybe it was a mistake in writing or direction, I don't know but for him (the son) to be upset solely over that seemed unrealistic but apparently that's why he was upset. I still found him annoying, though.
So, the bus driver is asked to sign a loyalty letter, and he refuses and in doing so he gets fired. It's centered on the whole Communism thing in the 1950s. They take awhile to say that (on purpose) but they get around to it half way through.
The "challenge", I guess is: should he stay fired or get his job back? Apparently the kids who ride his bus (who don't care about the politics of why he got fired) want him back and refuse to go to school until he's brought back. So, the school with parents, and a teacher, and the principal have a meeting with the bus driver, his wife, and son there. They discuss, heatedly at times, about freedom and conformity in accordance with loyalty, and they briefly try to explain it to one child even though there are several children in the room. The child doesn't care, he just wants his bus driver back.
They allow the bus driver to tell his side and then throw in a lot of propaganda points such as the teacher basically saying what is still used today (sadly) that her brother died for the freedoms Americans have and it's un-American of the bus driver not to sign a loyalty letter. That teacher needs to grab a dictionary and look up "freedom" as do many US citizens today need to do because they still yell out the same diatribe.
There's pros and cons given and then it's over and you never find out if he got his job back because that's the "challenge", you, at home, decide his fate...well, in your head. I can see why the show didn't make it past the pilot: people don't like cliffhangers or in this case: a non-ending. I know it's meant to make one think but it just didn't set it up that well and you can see why it failed based on that. I only watched this because Sidney Lumet directed it. Otherwise, I may have just passed.
