Watched it for Collin Morgan and ended up liking Sally Hawkins performance as well. I think she portrayed dissociation quite well. The side plot of their marriage was actually more interesting than the main storyline.
SPOILER ALERT: The whole "big reveal" at the end feels very fake and implausible. How big a hypocrite and detached from reality would you have to be to react the way he did to his wife's cheating when he was doing the same. Things just don't add up. Additionally, the mystery and supernatural element around Amondine just makes her seem grandiose and full of herself - her performance is superficial and unconvincing.
