Saw this yesterday and I'm still puzzling over all the questions thrown up by the ending;
SPOILERS
We're told that if you die in the virtual world you die in real life, if this was a VR headset freedom of movement thing then I could grasp that if you stab someone in VR they're stabbed in real life, but Alice is tied to the bed in the real life set up, how could she have done any real physical damage to Jack?
DH claims that the idea is if your mind is so entirely immersed in VR then your body would just stop living if your brain thinks you've died, but Jack isn't entirely immersed, he disconnects daily to go to work.
And when she wakes up from the VR world, presumably she's still strapped down, only with Jack's dead body next to her? What happened then??
And as above; the explosions? The plane? If he could suddenly earn enough to support them both once Victory came along, why couldn't he have done before? (Not that she'd have wanted him to).
Far too much left unanswered for me. Florence Pugh was superb though, and it's never a chore to look at Harry for a bit.
