I'm really impressed so far. The amount of characters and story is teetering on overwhelming (especially because I've never read the novel nor seen another adaption of War & Peace), but I'm following well enough. The battle sequences have been as insane as everyone else has described them, the scope in all the non-battle scenes is impressive too, the camerawork is frequently risky and inventive in ways that work, and there are some surprisingly surreal and philosophical sequences that are actually working for me and not feeling boring (I say that as someone who isn't a huge Tarkovsky fan). Here's hoping the remaining parts are just as good.
