Well, shit. I finally saw Amadeus. And was hugely surprised by its tone and accessibility. I was completely expecting something stuffy and pompous, but it's really just a good story that is solidly executed, with a world and characters that genuinely feel real (and modern). I'm impressed, and I will no doubt be revisiting it at some point in the future.
If you've put off seeing it for one reason or another, give it a go. I think the only complaint is the run-time, so just watch it when you're in the mood for a film of that length. Thumbs up though.
