i liked it as a psychological drama and after the tense bunker scene i thought he was redeemed quite beautifully....realistic too. Adding the actual end-of-the-world scenario seemed pure daft and far-fetched...just jarring...much like the raining frogs from Magnolia. Chastain i just can't abide her, she's naturally very unsympathetic and is unable to act her way out of it.
...all just my opinion of course, i think we agree the film was otherwise pretty good.
Different strokes for different folks I guess - that's the fun in healthy debate
Another film with an ambiguous (and probably 'Marmite-y') ending was 'Sound of my Voice' - Another modern classic
