This movie really was surprising.The special effects(better than "Gravity" in my opinion),the accuracy of portraying the technology of the time,the soundtrack,the camera work.It's a space- thriller inspired by real events (you can search the mission soyuz t13 or look for documentaries about the salyut 7 to find out that very few moments were actually modified).Unlike the movie "Gravity" physics are respected,so it's spectacular but has that "apollo 13" feeling (with less cheesy moments or fake dialogues),except for the first 20 minutes we spend the rest of the time in space with the cosmonauts trying to repair the salyut 7 and survive to all the unexpected problems.I was never bored until the end.Some people say that the movie has propaganda,not true ,like in a lot of American movies cosmonauts and scientist are the good guys and generals want to save their reputation and the reputation of the country ,it's a pattern we have seen in a lot of Hollywood movies.The movie shows respect to all space heroes ,even the American astronauts and the shuttle program in a particular moment.If you liked "Apollo 13","The Martian","Interstellar","Gravity" you will love this movie,it feels and looks more real (some scenes are actually filmed for real like the breathtaking launch sequence).All actors are good and human.I hope the bluray will also be released in 3d (in Russia it was an IMAX 3d release). I give it a 8,5.
