Bart-Mangled Banner is a fantastic Simpsons episode with a very well written storyline and loads of very funny scenes. It's certainly one of the highlights of the fifteenth season, I always forget about this episode but when I see it on I remember how much I love it, it's very risky, making several jabs at America, and the overall set up seemed like a disaster waiting to happen, but it ended being a truly great and unique episode. It had great potential at the end of the episode to have a second part, which I think would have been great and felt like a missed opportunity, it's a substantial episode so it would have made perfect sense to be a two parter, I would have loved to see the Simpsons getting use to a new life in New York, eventually moving back to their home town in Springfield of course, this was a great opportunity for another episode and the writers should do something like that more often, twenty more minutes to wrap up the story properly. It's very impressive how much is done in this episode, I find it very hard to believe that it's only twenty minutes long, the story takes many twists and turns, and the characters are taken to many different locations, this couldn't have been easy for the animators and the director deserves huge credit for the amount of work that went in to it. There isn't any other episode like it, Bart- Managled Banner is a very enjoyable Simpsons episode.
The Simpsons become the most hated family in America after a picture of Bart mooning the American flag goes viral.
