Great idea of making a retro style video, but only because of the 4:3 ratio it wont be oldschool.
The resolution, these effects and musics didnt existed/werent used 6-7 years before. And unfortunatelly i didnt understand the role of the Simpson guy ( creative, but makes no sense ).

If it wouldnt made to be a retro movie, it would be around 9 points. Unbeliveable scenes all along the movie. It was worth to watch. Great movie.
