The movie is based on a book and the actual title of the book in Bulgarian is "Vreme razdelno". The word by word translation of this in English would not make much sense as it would be something like "Dividing times". I would say that the actual meaning of "vreme razdelno" would more likely (in the context of the book and the hystorical background described in it) be "Time to take a stance" or "Time to choose a side". The reason for that becomes clear in the book (it cannot become clear in the movie) where towards the end, where the leading men in the village are being held prisoners of the Turks (or the convereted into Turks jannissaries), the major character Manol meets with Syuleyman Aga, who is being sent to meet with the Ottoman Empire's Sultan for the purpose of supposedly being given an award, when in fact they kill him and he never returns to the village and his wife (the book implies that this is because his sympathy for the Bulgarians and his refusal to forcefully convert them to Islam, and his aversion to violence). Manol and Syuleyman Aga meet in the prison, where Syuleuman Aga says to Manol that even though he has lost all his powers, he still has enough to set Manol free. Manol asks about the rest of the men. Syuleyman Aga says that regretfully he can't do anythign about them. Manol says that he will stay with his fellow villagers in prison awaiting his death. Syuleyman Aga says that a force bigger than Manol, and the villagers, and Syuleuman Aga himself, has come upon these lands, and everyone must pick a side, nobody can stay in the middle ("doshlo e vreme razdelno" - "a dividing time has come" or "a time to choose a side has come"). Manol answers that he has picked a side, that's why he is staying with his fellow men, but says he thinks Syuleyman Aga is still trying to stay in the middle. Syuleyman Aga realises Manol is ride, bids him farewell, and leaves to meet his unfortunate fate (which he knows in advance).  
Although many would argue that the book was a political order during particular time in the Bulgarian history during the socialst regime, the book is still based on actual historical events that took place in Bulgaria (in particular the Rhodope mountain region). The book is also nicely written and has both literary and historic value. I do suggest that if you have a chance to find it in English that you read it, then the movie will make a lot more sense. As it often happens (at least this is my observation) when a movie is based on a book, rarely the movie is better than the book. I've always liked to read the book and see the movie so I can reach my conclusions. 
The violence in the book and in the movie is very different than violence from American perspective. It is not plainly shown as in mass murder scenes, etc. Instead, it is implied. But I think it is a very heavy violence - a violence where virgin girls are mass raped, men are being beheaded, impaled, or torn into four pieces by tying them to four horses and then getting the horse to ride in four different directions, people are starved, or kept with no water, mothers are forced to make a choice between converting or having to watch their children being slaughtered, and a little boy has to kill and cut off the head of his brother for the purpose of stopping the violence. 
Maybe all of this is exageratted, I don't know. None of us has lived through this period. But please do not think, that beheading, impaling, rape, or forced conversion did not occur during the period of time when the Ottoman Empire was coming from Asia and invading Europe (historical accounts of these events can be found in other European countries as well, not just Bulgaria).
