Definitely the weakest of the trilogy, but I'll never not find this formula entertaining.
How I imagine the producers pitched this to Villeneuve:
VILLENEUVE: I dunno, this seems sort of hopeful and uplifting. I prefer dark stories about serial killers and drug runners. I don't really see why you came to me, to be honest.
PRODUCERS: Did we mention there's a giant spider creature thing?
VILLENEUVE: I'M IN.
(This joke for the thirty people who saw ENEMY).
