This is a Ridley Scott and all, sooo I shouldn't have been too surprised by the contrivance of the ships doctor going mad, dousing a mid-winter carnival for desperate sailors in lighter fluid, touching it off then self-immolating, moments after the coincidental return of the main Innu woman character sans tongue, but I was very surprised.
In fairness, with a bit of reducing-the-number-of-key-characters-to-keep-track-of, I think that bit's straight from the book rather than Ridley. He's a producer on it, did he do any more than line up the finance for people?
