Mark Duplass two-person movies aren't great (no matter his co-star). "Blue Jay" sucked, "Paddleton" was meh, and now "Biosphere" is bizarrely odd - and NOT in a good way. After an apocalyptic event it seems Duplass & Sterling K Brown (likeable) are the only survivors, in the small titular dome Brown built... where inane bro-banter morphs into outlandish, cringeworthy nonsense under the thinest veil of serious sci-fi. Written (by Duplass & debut writer Mel Eslyn (also its debut director)) like a high-school homework play, it has too many gaping plot holes to list, adding to a seemingly deliberate tone of surreal implausibility. Original it may be... but good, it def'ly is not.
