They led me to go read the books, the metro series of books is great if you like post-apoc. And if you enjoy them, try the Night Watch/World of Watches series. It's supernatural, focused on a quasi-governmental department that keeps the peace between the light and the dark magic communities, very gritty. The Nightwatch/Daywatch films are really good too, such a shame they never made the third.
There's a certain mind set in all of the Russian literature I've read that I find extremely appealing. I haven't read that much, but found that same mindset even in the older stuff like War and Peace, or Master and Margarita.
