I rarely stop to review movies, but this movie deserves better. Reason I decided to watch it was that I am a SF fan, and the plot from IMDb was provoking. Managed to find proper subtitles, so I was able to fully understand the dialog, although you can find the movie with English subtitles hard- printed on screen. The international name seems to be "Paradox Soldiers" if you want to try to find it, by the way. Indeed there seem to be a few connections to a previous movie, but you just need to pay a little attention in the beginning of the movie, as the connections are explained well enough to understand what is next and make the proper connections, and simple enough to not ruin the whole movie and let you guess everything that's about to happen. Actually, I wonder if there is indeed a previous movie or they are just invoking actions which have not been portrayed in the story-line to enable them to focus on the main plot. The "2" in the title might give it away though :) I must say you need to know a little history (have you heard about the World Wars?) or pay attention (again) in the beginning of the film to understand there was (both in the present and in the past) some tension between the Ukraine Russians and the Russian Russians, as you will need to differentiate them also when going back in time along the storyline. You will have no problem understanding the fight with the Germans though. Script is good, actors are doing a great job, they are well-defined as characters and perform really well through-out the movie. There's a bit o a love story embedded, if you fancy that, but the movie is a war action movie with excellent was scenes and a science-fiction pretext to justify the plot. If you like being challenged a bit and you don't have preconceptions about foreign European movies, this is a must-see. I will look-up the first movie of the series and see them both again.

if you did not know this is part of a sequel it will be the most confusing film you have ever watched. 4 guys arrive at a war re-enactment where half the people are in WW11 uniforms and the other half are drinking and listening to a rock band (maybe thats what they do at war re-enactments in Russia). they are blasted back in time and one of the guys seems to know everyone he is also in love with a girl he has only seen in a photo. This girl gives birth to baby that they then give away. They are then blasted back in time. MOST CONFUSING FILM EVER. My advice- only watch this movie if you have seen the first part of the sequel.
