I liked this way more than I expected to. Kinda loved it, actually.SPOILERS
There's a simplicity about it that I appreciated. I think revenge stories are best done that way.
The interpersonal interaction was limited enough, and the general human conflict was pervasive enough, that the gestures of compassion were quite powerful. The conditions and circumstances are so harsh that you're just aching for people to get along, and when it actually happens in those brief moments, it's so moving. This (and less the revenge itself) was my takeaway.
The bear attack was absolutely mindblowing. Yes, I was surprised that his skin wasn't completely shredded off, but I think they did focus more on the pummeling and the bone-breaking. I would certainly say he seemed to be suffering enough after the attack.
I have trouble understanding complaints about the film's length. Perhaps it's because I was in for a punishing experience, but I could have easily taken another 30 minutes. While The Hateful Eight felt even longer than its actual running time, I wasn't particularly aware of the passage of time watching this. There's so much beauty constantly; how could you not want more?
Trying to think of things that actually bothered me, and I have to be honest, I'm mostly coming up empty.
Some of Tom Hardy's lines were a bit on-the-nose. But that makes sense for his character.
It did puzzle me how crowded the vast wilderness seemed to be. I suppose that can be explained, though; this is a high-traffic trade route, and there are a lot of people looking for other people at the moment.
Side note: I think either Leo's complaints have been blown out of proportion, or he's done some clarification, because this is what he's said recently:
"I think certainly the conditions that we had to shoot in were the main thing, the freezing cold temperatures. But everyone that was a part of this movie – including myself – knew from the very onset that we were getting involved in something that was going to be incredibly challenging." (source
