Too Much Music
I happen to be a musician and I love Mozart, but I saw the original Broadway play AMADEUS and the focus was on character motivation; there was music in the play but it was all in the background. Putting some of it on the screen may have seemed like a good idea at the time but in the end they put in too much; the extensive scenes of Mozart's and Salieri's operas being performed become tiresome after a while and the resulting film is bloated and top-heavy with music. The end result is that the thrust of the drama is muted and the story itself ends up being lopsided. The original play was more about Salieri than it was about Mozart; by including so much of Mozart's music Forman switched the focus of the film from the Broadway lead to what had been, and despite Hulce's wonderful performance, is still a second banana role.
Oh God. There's nothing more inconvenient than an old queen with a head cold!
