In fact the most of historical facts in "Tsar" are truth, you can read Karamzin, Kostomarov, "Житие митрополита Филиппа" and a lots of articles on the net. Tsar really was very religious, he spent a lot of time for worship. He interprets the faith in his own way. He really killed a lot of people because they were against his politics. He really punished his warriors for their faults. He knew Philip from childhood (though they were not friends), He sent him a head of his nephew. He kiled him. And so on. The only thing they made bad in the movie is the lack of teeth in Ivan's mouth. Terror had a place. 16th century was a really bad time to be born. And again, the movie is not about historical acuracy (though it is accurate enough), but about faith. And this topic is well covered in the movie. And "the guy you know" or (smth like this) basicaly not a critic, he is a comedian. So i still can not understand your argumentation.
