Amadeus
Basically:
Mozart is Spongebob and Salieri Squidward.
It tells a surprisingly accurate biography of Mozart while presenting us a disproven theory about Mozarts death (In this case a what if scenario), which Puschkin heavily supported with his infamous work.
When watching this, please be aware that Salieri didn‘t kill Mozart and their rivalry is exaggarated. But since this is a film, there is nothing i can point out about this work of art, that hasn‘t been great.
