Oksana Akinshina's performance as the title character received universal critical and popular acclaim with reviews praising in particular, her naturalistic, subtle and nuanced approach to such a tragic character which helped the movie and Lilya feel even more realistic and sad without being purely manipulative tear-jerker or award-baiting flashy spectacle. It garnered her multiple European accolades and many consider to be one of the finest breakout performances by an young actress, as well, one of the best female acting of the 21st century.
