I wouldn't advise you to choose those films which were made after the 1990s. Modern Russian cinema is not very good... I liked "The Barber of Siberia", though, that was a big hit. The tv series "Brigada" (drama about criminal world) was a huge hit as well.
My favourites are older movies, they are all classics:
Служебный роман (romance/comedy)
Девчата (romance/comedy)
Весна на Заречной улице (love story)
Иван Васильевич меняет профессию (comedy)
Кавказская пленница (comedy)
Операция "Ы" (comedy)
Бриллиантовая рука
А зори здесь тихие (war drama)
В бой идут одни старики (war film -- sad in places but not oppressive and not without humour)
Офицеры (war drama)
Три мушкетера (screen adaptation of Dumas' novel)
Человек-амфибия (sci-fi)
Невероятные приключения итальянцев в России (comedy)
And so on, and so forth...

Be sure you have the subtitles, though. You can find them at
subs.com.ru, for example.
