First off, don't pay attention to frostvortex's review since he/she is a troll spreading lies.
Panfilov's 28 battle is not a myth and is documentally proved by both Russian and German sources, the only inconsistency is the number 28 which is not correct. There were more than 100 fighters, and the movie also reflects that.
The movie is very dry but unique in its language. Don't expect anything Hollywood-like. It does not depict complex plots, flashbacks or tear-filled love story, no bursts of emotions, it does not have a main hero. It is almost documental since the viewer is indifferently thrown into one day of Panfilov's men life without being much prepared for it. No one cares about being introduced or explained to the viewer as everyone are busy preparing to fight the Nazi tanks. But each character's individuality can be recognized though the dialogs.
Next comes the battle which is just great. You have to hear that sound. You have to see it. No gibs, no gore, but it is really scary ang gives great impression of what Red Army soldiers have gone through. It literally puts you into their trench. Also, no super-heroes. Just the ordinary people who modestly gave their lives to stop the Nazis.
The level of realism and historical details is very high. You will see proper explosions, proper guns, proper tanks, proper uniforms and other things from that exact time.
Go and watch it.
