I'm afraid this movie will share the fate of Mike Judge's "Office Space" and Ślesicki's "Show". Both movies are great, but failed at the box office, because were unlike their directors previous works, and thus were not what people expected.
Anyway, "Ile waży koń trojański?" is a great movie. It's based on a "what-if" concept. A woman wishes to undo some mistakes of her youth, and she is given a chance to do it. She accidentally finds herself back in 1987, 27 years old, in communist Poland, but with knowledge of her future (which she wants to change).
