A great first two acts (on that note, the acting is excellent–Cheadle is hilarious) with its outrageously funny satire of academia (see the swirling professor duel), quirky family drama (the overlapping dialogue is edited to perfection), and oddball apocalyptic comedy all mashed together and drenched with existential dread. The third act is no less full of things to dissect but the characters make weird choices and it kinda loses the plot, literally, and thus any sort of momentum it had too.
