At the moment I'm writing this, "Falsifikator" has rating 5.7. I guess people didn't like another comedy making fun of Tito's time and showing us (just like "Underground") that all the Yugoslav history is more or less manufactured.
But I see something else here; perhaps that's not what Marković had in mind, but here it is.
What I see in this movie is the never-ending Serbian (or Yugoslav, as you like it) tendency to cheat the system. Oh, how cool it is to cheat teachers in school! On universities: what's wrong with letting students pass the exams although they don't understand what the course is about? (Not realizing that some of them will teach your children in schools afterwards.) And why should I insist on the guy from grocery store giving me a receipt after I bought something from him... he's only stealing the tax from the state. (But who really gets cheated here? The people who get paid by that state!) And it's OK to have an illegal job, right? Your boss keeps the money he should give to the state, how clever of him. There are so many examples... No wonder that the complete contemporary Serbian politics consists of tricks and deceit.
In the movie, after over a thousand of forged diplomas, our hero begins seeing judges winking at the offenders, and doctors believing that a simple cold is a lung cancer, all with his own hand-made diplomas on the wall. While in prison, he also realizes that even crimes can be falsified.
Some of the acting was also memorable. First of all, Tihomir Stanić is very good in the title role. But pay attention to Sergej Trifunović and his unusually straight acting; I like him very much here. And Ratko Tankosić, a specialist for one-minute roles, is simply hilarious as the judge; not for a moment you suspect that he knows anything about his job!
Well, that's all. I guess the message is: try to be open-minded with this movie, and not to dismiss it before you see it.
