What makes it different from others?

Easily the biggest piece of Right wing non sense propaganda I ever saw.

By the time the dramatic fireworks start popping off, each one feels earned.

Excellent and certainly provocative... If nothing else, the film is a real conversation starter.

Scott Adkins never dissapoints in his action packed movies. All his Boyka movies are great!

This is the fourth in the Undisputed series, a series that unusually has been getting better with each film. I expect if you are watching this movie you are already a fan of Scott Adkins (a vastly under rated actor) and his character Yuri Boyka and know what to expect. This time though we see more of a story and a chance for Boyka to develop from just a fighting machine. That being said there are as always some fantastic fight scenes.Boyka: Undisputed is about the heart of a warrior and the heart of a man who will never be beaten.

*SPOILERS* I really don't like this film I love Scott Adkins and Undisputed 2 and 3 were the best films in my opinion. This movie to me fails haven't we see in other kickboxing movies in which a kickboxer takes another life and he mourns for it yes we did. I saw it in Bloodfist II, Desert Kickboxer and I think was also in Deadly Bet with Jeff Wincott. So Boyka kills hiss opponent by accident and he feels remorse so he wants redemption again and he find's out the wife of his opponent is in debt with local mafia in Russia and he decides to fight to set her free. Haven't I see that before the plot yes I did it was in Gladiator 1992 with James Marshall and Deadly Bet in 1991. In Gladiator James Marsahall's dad was owning a mob collectors a lot of money and Tommy (James Marshall) has to fight for money in the boxing ring to set him free. In deadly Bet Jeff Wincott is a gambler in Las Vegas after his last fight he loses his wife, respect and money and then he trains and goes against his opponent to set his wife free. So yea this movie steals ideas and scenes from this movies he stole it from Bloodfist II, Desert Kickboxer, Gladiator (1992) and Deadly Bet. That is why I don't like it cause it is not original.This movie has not the director Isaac Florentine in it from Undisputed II and III who were great absolutely amazing movies, this movie to me fails. Todor Chapkanov is the worst director and I really didn't care about Boyka and his self pitting retarded.The villains were not likable like they were in the last two movies and Scott Adkins didn't you do the same thing when you killed a kickboxer in the tournament oh yes you did in Hard Target 2 why can't you be original?!The only thing i liked in this movie is the good fighting scenes. The music score was terrible, the plot the actors everything fails flat. There was not any good music score in this movie at all like the last two good films had.This movie to me is overrated trash and it is not good in my opinion. Lionheart with Van Damme is much way better movie in my opinion than this crap! Score F 1/10 I don't care about this movie I love 2 and 3 to death I don't like this one.

This B-movie got some nice fights and like other martial arts movies there is terrible acting and story line going on as tradition is in these all out testosteron flicks.But actually it almost becomes a comedy when the actors speak, i had some good laughs.My expectations weren't high so i wasn't disappointed and enjoyed watching the movie.
