As for the rest of the sentence... I'm not sure what point you're making. It's not quite in the vaudeville pop mash-up territory, is it? It's not like they've made a silent black and white Transformers film. They've used a medium that fits with the story they're telling to enhance the atmosphere.
It's a modern film using story telling technique that's close to a century old. For no other reason but to cover its simple, predictable, mostly boring, naively told story, that you wouldn't look at twice if it wasn't for the fact they weirded it out into silent movie. And the effect is not there to make a "girl with a red coat in the middle of black and white war movie" impact, it's there because otherwise it would be tuesday evening hallmark movie at best. And awarding that story with best film and best leading actor, just because story telling method is intriguing, retro and weird, is a bit too douchey and connesseur for me. It's like that year when Chicago won. To put this film next to Amadeus, Platoon, Last Emperor or One Flew Over Cuckoo's Nest for the top award is a slap in the face to the film makers and cinema goers together. Granted, it was a bad year for movies. It was bad enough to watch William Bradley Pitt and Sean Penn try their best this year to get into every looooooong, boooooooring, self indulgent snooze fest possible with "please nominate me" practically tattooed on their foreheads. But making The Artist Best Movie is a bit of a joke. Let's not be afraid to say it - the foxtrotting thing was boring and got old as quickly as a mime from Covent Garden doing glass wall routine.
