The way they use 3d cgi's is awesome. Other cgi's would make my eyes bleed but that wasn't the case with this movie. The snowy environment, and intentional avalance at the first battle was awesome. The environment in second war was really awesome too. They really nailed this job. Fights were pretty enjoyable. Only issue is KV-1 lived too long. I mean really long. Idk if it is historically accurate for it to not get penetrated from those shots but I guess it got 3 shots to left side of its turret and was still working completely fine until they shoot it from an higher position.
