A shallower version of The Terror & Revenant. Worth it if you're keen on 1800s whaling history. Lacks characterisation, horror and despair (had to skip the seal/whale killing scenes, but that didn't detract much). A tired ending (that polar bear symbolism again). The environment is sublime, the score is good too (they went as far north as any drama film crew ever has).
Characters motivations are muddy & I don't care enough about them (e.g. is the surgeon gay? did he hurt an Indian boy himself, or does he just feel responsible?).
Why not show real opioid withdrawal: diarrhoea, vomiting, sweats, aches? People usually don't feel 'stronger' after, it can take 6-12 months for the brain to reset.
The plot line with the cabin boy wasn't logical (why hide evidence on board? wasn't the rapist carrying a disease?). It supports the surgeons flashbacks & make him empathetic, but there wasn't enough scenes between them (or between him & the gay sailor he defends) to make the surgeon truly decent.
Acting is pretty good (from Farrell as deadly Drax, O'Connell as the addicted surgeon, Moller as the wise Norseman and Mullan as the purpose-seeking priest).
I have massive problems however with Drax's existence, someone so evil simply would of been killed many decades ago.
Grahams native Scouser accent appears on too many occasions (he's supposed to be from Yorkshire!).
I predicted what was going to happen, well before it did. In contrast, even knowing the history of Franklins expedition, I was still guessing at the turns Terror took. I never felt that O'Connell was in any real danger (they should dispose of the 'dreams as premonitions' thing).
