I'll retract my statement.
I thought it over, and there were a few things I considered plot-holes that actually turned out to have good explanations.
Still, there are a few things that, while they may not be plot-holes, are really illogical.
The whole incident following Tatum's nut-shot. It makes absolutely no sense for him to stay down there. Either he shoot some more from the basement or he get up before they're able to regroup. Staying down and eventually surrendering is just idiotic.
And how they were so sure Kurt Russell and Jennifer Jason Leigh were going to stop by Minnie's haberdashery? Sure, there was a blizzard coming, but it was quite sudden. Knowing they would end up at Minnie's seems pretty convenient.
