All Paul W.S. Anderson flicks should have the majority of their runtime focussed on two characters who practically cannot talk to each other!
Joking aside, though, I do think that one reason this plays more engagingly/less numbingly for me than what I remember of all the various Resident Evil installments, or even Pompeii, is because of the two-hander section in the middle, which serves to filter out some excess action and distraction, giving us a couple of movie star heavies…
