Just watched this tonight. Damn, that was a fun ride. Mad Max in Lapland vs Nazis, is the way I'd describe it. Dark, violent, pretty grisly at several points. My wife loved it as much as me, and she tends to shy away even more than me from the uber-violent ones. I think it's b/c there were clearly evil dudes being killed/dismembered etc plus women being enslaved & abused.
I'm still kind of trying to figure out why I like some movies, like this and The Suicide Squad, that are very violent while others like John Wick, I didn't. Maybe it's b/c Sisu & TSS are a little more removed from reality, and have some humor? (Albeit VERY dark in Sisu.)
bmoney - yes it's mostly in English, though there isn't a lot of dialog especially from our hero.
