Having seen nearly everything of hers except for The Bling Ring, I would saw this is in line with everything she has done. I think her strong suit has always been creating a moment of mood without it coming off completely as some forgettable æther. Or you can call it maximal-minimal where it gives you enough to know what is going on but leaves you with enough for you to ponder as you deem fancy.
I will say it is refreshing to see a film go for brevity with 93 minutes where this could have easily been a two hour plus indulgence. Also I had to suspend my disbelief with its setting because I know something a bit about that one .
Oh and one more thing ...
I really liked the Phoenix contribution - and not surprising given this is Sofia - but I wonder also if this was almost the "PaulStretch" effect on the Monteverdi. This is not to disparage it. If anything, it's appropriate given that it's about creating an atmosphere and a ghostly impression of what had happened, both within the film and even beyond it. In a way, it reminds me of why I like artists like William Basinski and Leyland Kirby.
